There’s a lot of juice and good vibes that make this game fun to play (the music and screenshake, predominantly).
Once you run around for a little while it becomes hard to lose - enemies don’t turn around when they hit a wall so they get bunched up in the corners, and it becomes easy to sit somewhere they can’t shoot you and pick them off.
That being said creating a platformer with 3 weapon types in 3 days is an impressive feat, so well done
