Nice little game. I especially liked the simple graphics (eventhough I think it glitches sometimes) and the music which fitted the game very well. Some things I suggest to improve in case you continue to work on it after the jam:
- The character is always looking right, eventhough I walk left. This is sometimes a bit misleading, especially when you shoot and you are not sure in which direction you shoot. Just changing the direction of the sprite would be the easiest one.
- The dash works only to the right.
Anyway, congratulations to a nice game!
