I absolutely loved it! Best game I've played in the jam so far.
Really polished, tons of really well designed levels. Each level was fun and memorable. And that last level was tough as hell, but so fun and rewarding when I got to beat it. I spent a lot of tries on that. A death counter would have been really funny.
The graphics look really good, the sound effects and the song are really good as well.
The shooting and death effect felt so satisfying. It was a nice mix of puzzle with fighting enemies, loved it.
The rewind mechanic itself was super cool and well done. You needed to know when to use it, how, there were different ways you could use it. You did a great job! It was also nice that you could get stuck and then need to restart the level with R, lead to many aha! moments.
The dialogue at the start was really funny, chill and helpful. Really nice way to teach the main mechanics of the game.
Overall awesome job with this game! I would definitely play a version with more levels for hours and hours in my free time. Congratulations!
