In short, it's a good retro platformer with some serious technical problems.

Yes, it's Flashback. Feels like Flashback, plays like Flashback, looks like Flashback, except it's even more low-res than the 30-year-old original. The controls feel a little stiff now, but once you get used to it, it plays very well. The game itself is very pleasant.

Except for one thing. There's no save on exit. You save at the beginning of each level and that's it. In a game where you can easily spend 30-60 minutes in a level. I mean, there are a lot of checkpoints, but you don't keep them when you leave the game. Really? Do the developers know that people have real lives? That people often have to leave the game and don't want to replay the whole level? My playthrough would be about 1.5 hours shorter if there was an exit save, and that's only because I managed to have an exceptionally long session.

This is made worse by technical problems. Setting the game to full screen doesn't work half the time, and when it does, it actually prevents you from alt-tabbing to another application. If you try, the game immediately takes the focus back. So you can't quit or switch to another application. I felt like I was back on 8-bit. Once the game lost the sound and once the game stopped accepting any input - in both cases forcing me to restart and lose all the progress I had made in a level.

So, as I said, the game is fine, but all of these problems take away from the experience.

Great retro style game for lovers of Flashback and Another World! :)

It's all fantastic except final boss needs to ruin the fun and leave me with nothing but anger for this game.
Still great game, fantastic pixel art, cool level design, tight "campaign", I'd be so happy if it weren't for an annoying final boss. "Thanks for nothing" he says passive-aggressively. Still, great experience overall.
