Positives:
- The shooting feels very satisfying
- The art style with solid colors and black outlines is very nice.
- The music is mostly pretty good.
- The story is quite good and mysterious. I like how the characters speak so casually, it gives the game a unique voice.
- Seeing friendly versions of the enemies in the town is a nice touch that builds the world.
- The "!" icons for pits that you will die in (rather than go to another screen) really help.
Negatives:
- The platforming doesn't feel that great, and especially the way the shooting interacts with it feels janky and isn't very fun. Needing to focus on aiming to help your jumping is a bit much IMO. It's a good idea though. Maybe it could be better with some changes.
- The first music track has a constant ringing sound in it which is quite painful.
- The level design is not great. A linear world where you have to run end-to-end every time you get a powerup is not what I look for in a Metroidvania.
- I fell out of the world a few times. Once when going up the long wall on the left hand side, I was shooting to push myself against the wall when I switched screens and went through the wall. And once when I was descending that section, I jumped as far as I could to the right to try and get down faster, but I went off the right side of the screen and the screen change didn't trigger.
- The instant respawn after falling in a pit makes it quite easy to die again straight away.
Overall though, nice job!
