It was a great experience!
I adore the simplicity of this game. Most of the submissions in this game jam have gone very hard with the visuals by forgetting to stay with the jam's restrictions, but this game was on-point in regard to that!
Apart from those, I adore what you have done with different types of enemies. It was fun to learn their movement and fight them.
I think the game can use a lot of polish and turn into an amazing experience overall, but even in its current phase, it offers a lot!
Solid entry, good job!
