A note about my judging: My rating scale starts at a baseline 3/5, anything good done raises a score, things that are less good can lower a score. Genre is rated generously. As a game-developer I know that when giving feedback, while I can give suggestions, it's up to you as the developer to determine what accords with your vision.

I don't know what's happening here.
Enjoyment 2/5: I found it enjoyable for about 2 minutes and charming overall!
Execution 2/5: Please do a much more thorough job of explaining what's up to the player. In the screenshot above one would normally expect a tetris-like game with a gun to be in a lose state by all known Tetris-y conventions, yet I've left the game running while reviewing it (with no input) and I'm on level four. I can't stress enough how little I understand what I'm doing here.
Sensory 3/5: The music is neat. The colors are less so, but they don't actively hurt my eyes.
Metroidvania 1/5: This is not on-genre for this jam in any sense I can meaningfully score above a 1 for. It's really just a classic puzzle game but with a gun, as far as I can tell.
Overall this has potential to be a quirky and charming (if janky) game. I recommend dropping all semblance of having more than one camera angle (focused on the player, or maybe even holding still) and focusing in on ways you can make the mechanics and scoring much more obvious to players. The quirk and charm are there but they're being overrun by confusion and possible jank.
