This is really one of my favorites! Did you do art by yourself as well? I really like the sound effects. I must say it feels super polished for a game jam game. I was also SOOO suprised when the arrow poped up and I was led into another level! Did not expect this scope...
In fact, I made it into level 3, but now the bouncing ball enemies are just to strong for me.
Anyway, I am really impressed! Good work! :)
