The level of love in this was apparent from the thumbnail alone. As soon as I saw it on the page of thumbnails I thought, "that one!" I'm glad the game didn't disappoint. It's tough when you put too many controls and mechanics into a jam game when you know most users are stopping in for a short play, but I thought you did a great job with the UI by having the mouse and spacebar on screen with their actions represented. I adore the art and animation. The crowd cheering me on kept me pumped up and the mice with guns are hilarious.
The player space felt a little too tight. I know you want to keep us in the action, but some room to move and plan out moves would be great and help build anticipation and let you design bigger enemy attacks with more telegraph movements. I found myself at the beginning of many rounds clearing out space to move around. Overall though, it's been one of my favorite games in the jam.
