Your game is amazing! I just wanted to smash and smash! :D My only real concern was the load time on my browser. The graphics and sounds were good. I could tell you guys rushed the menus, but they work! This is a great first jam!
Aside from some basic concerns like the targets not being obvious the first time you play, or knowing what is break able and what isn't.. the games fun!
You could polish it a little here and there? Sure. But the bones are there! And I am shocked with the visuals you were able to achieve.
I also just did my first game jam--- ! I am hoping to get a few more patches through before the deadline! If you see any bugs let me know! :D
