I bought this game at full price, but you shouldn't. Here's why. Wizard With A Gun, which I had been excited for since it's announcement, had a lot of potential and a promising start, but it was and in many ways still is an unfinished and half-baked game. And most unfortunately, Galvanic Games has shut down, meaning all development has since ceased. With the state of the game now, I simply cannot recommend buying the game at full price. Now, let's go over the specifics. We'll start with the negative stuff, to get it out of the way.

Bullets - Starting off with a big one, bullets in Wizard With A Gun lack depth. There are about 8 different bullet categories, but it's really easy to only stick to one or two throughout your entire playthrough, even on the hardest difficulty. With each weapon only having 2 slots for 1 specific bullet each, you're very limited in potential combos or synergies. To add to that, such synergies really cease to exist. There was a lot of potential for mixing and matching bullets of different types/elements, but each element seems very self-contained, with very few ways for them to bounce off one another in any meaningful way. Additionally, since only certain bounty enemies have elemental immunities, and fully upgrading any particular bullet is rather expensive.
Combat - You'll find this is a recurring issue, but combat itself is pretty shallow too. This is, in part, because of the bullets issue, but also because of the enemy variety. There are quite a few enemies, but many of them fall into a particular repeating category and only are separated by their designs and stats. Take the bandits/outlaws for instance. Each biome has their own version of these guys, who like you wield guns. They can have one of four weapons ,and despite the fact that when they drop their weapon it will have both slots filled with particular elemental bullets, they only use basic damage-dealing element-lacking bullets in combat. As for the rest of the enemies, they generally only have 1-3 attacks, meaning encounters can get very repetitive very fast, and after a certain point you'll just start ignoring enemies altogether.
Gameplay Loop - The loop of the game is serviceable, but again shallow and repetitive. Each run will typically have one of two purposes, with their own maps of how you can expect them to go. Need resources?
Go out -> gather said resources (breaking stuff or killing) while ignoring enemies you don't need -> return.
Going for a gear? Go out -> look for gear / use one of those handy little books that immediately pinpoint a gear's exact location, all while ignoring enemies you don't need -> Find gear -> kill thing for gear -> return.
Should you die at any point in these, simply start back from square one. While not necessarily bad, these loops do not change at all, aside from what particular threats or resources you're looking for, up until you get to a boss gear. Add on to this that the resources themselves are often just iterations of themselves. If it's a metal, break the metal things. If it's a wood, break the wooden things. If it's a rock, break the rock things. Every environment has a different version of these resources, and they're the ones you need the most of. There are more niche resources as well, but generally to get them you either kill/break something with a specific element, or put a item in your element's specialized processor and wait. Again, not necessarily bad, but lackluster.

The World - Not quite a weakness, not quite a strength. The environments are fairly plain past a certain point. A few areas have little decorative objects placed about with minimal purpose beyond aesthetics, which is lovely, but it's applied minimally. However, each area does have their own unique manner of generating the world and their own own colour-palettes, meaning the different environments are very visually distinct from one another.

Art - Wizard With A Gun has a very unique and appealing art style, and generally good designs. While, as mentioned, the environments can be a bit plain at times, the enemies' visual designs are just really neat, and the different comsetics you unlock by scanning certain things are all interesting, with fun ways to mix-and-match for your desired character.
Music - I love Wizard With A Gun's soundtrack. Like the game's art, the soundtrack has it's own unique style, and the atmospheric tracks fit the environments well, especially in The Tower. When needed, the music really does well to set a sense of urgency, and the boss themes are just incredible. Speaking of bosses...
The Boss Fights - Unlike most enemies, the bosses of Wizard With A Gun have a decent variety in their attacks, and are fairly unique in many ways. They have stand-out designs, interesting albeit fairly simple personalities, and great themes. I always looked forward to these fights, though my only complaint is that they're still fairly simple, and overall pretty easy even on Outlaw difficulty. That, and there's one "boss" that just kinda sucks. They're the second-to-last, and while it's fairly unique from the other bosses in where it takes place, it's not really unique in much else.

The Base-Building/Decorations: I've never been all too big on sandbox elements in games, so I can't comment too much on this particular aspect of the game. But I think the decorations look neat, they're just a touch pricey if you're looking to overhaul The Tower, especially the floors.

For what it's worth, I really enjoyed my time with Wizard With A Gun, and I'd like to get a group together for a multiplayer playthrough at some point, but it's hard for me to recommend it at full price knowing that the game feels unfinished and half-baked. It's a great game, but maybe it would be more worthwhile to get it around $15-20 rather than $25. Overall a solid 7.5 out of 10, I just wish they had more time and resources to perfect the game that much more.

If you like games like Dont Starve and/or Cult of the Lamb then you'll love this. It's got a great art style, soundtrack and some decent depth in its mechanics. Combining oil & fire bullets to make warplflame is ALWAYS fun.
I bit more lore and story would be nice, but the gameplay is still a very fun loop. For the price, expect 15-20 hours to complete (shorter if you want to blast through it).

Very pretty, very fun, great gameplay loop
