This is not the best game on steam. It's not even in the top ten I've ever played.

But Bioweaver, and its counterpart Bio Prototype, are both really really good games.

The original game, Bio Prototype (BP for short) was essentially Vampire Survivors with a twist. Level-based 30 minute action where you progressively grow stronger and stronger until you die, then restart.

Bioweaver (BW for short) took that concept and changed it significantly. Now, you are simply playing a game like Path of Exile where you progressively grow stronger and stronger by gaining infinite new organs, mutating them into slightly stronger and slightly superior versions of old ones, making complex builds to mow through enemies that can be drastically scaled up in power as needed to give even better organs and better stats, so on and so forth.

This game's organ-building system is extremely complex and fun to delve into. Even just grinding and seeing new organs constantly dropping from enemies gives me a constant burst of dopamine. I played 30 hours in the highly restricted demo, and the actual full game is WAY better. I can't wait to play this at work in 5-10 minute bursts every lunch break. I am hopelessly addicted! It just keeps getting better and better the more I play!

If you like autistic build-prepping a character to develop new powers and abilities through complex interactions, play BW. It is an utterly unique game unlike any I've played before. Well worth a measly $7, let alone nabbing it on a 30% sale like today!

It's about ten hours of content to beat the game and complete the 30-floor challenge mode, or a few hours less if you land on a busted build.

The translation's kinda jank so there were times I was wondering what various mechanics or powers actually did. The fact that all of your brains are active simultaneously should really be explained better at the beginning.

Overall, pretty fun while it lasts if you like experimenting with weird game interactions and going "I wonder if this works?" But once you win the game by making a build that deletes everything, it runs out of content pretty fast. The interesting part of the game is farming up organs and the relatively low capacity per brain limits how much wacky interaction-chaining you can actually do. Not to mention that there are a few replica organs that are just obviously superior once you understand how they work. Still, the game isn't shy about actually paying off good builds by letting you steamroll levels so it's entertaining once you figure it out.

The game is exactly the same as its predecessor, with almost no combat complexity and entirely based on grinding the same exact scenario over and over. A box shaped stage with random sprites approaching you at a constant speed. So combat is just a build simulator aside from the occasional boss.
The monsters fit no specific theme and aren't really any different from each other. Hitboxes wildly mismatch the sprites as well.

The idea of organs is interesting in theory but locked behind poorly balanced currency and capacity gates, not to mention the borderline gacha system of a store and crafting, with large number ranges (That barely improve your organs even at maximum values) and tiers; unnecessarily complex beyond just "more randomness with your randomness so you can grind more currency with no guaranteed improvement"

Also full of what is clearly either AI generated or just soulless art and "story", and without a declaration if so.
