This was a well dome jam game! The controls felt nice and the gameplay was slick and fun! It started off a bit too difficult, meaning you almost had to be lucky to get past the rooms. Even then, though, it was lots of fun and was really interesting to play through. I also enjoy the different weapons and enemies! They added some good variety to the game. It'd be cool if each enemy and weapon covered the room in a different way, such as an enemy that had zig-zaggy bullets.
I enjoyed playing this a lot! It's a good entry!
