It's fun, but gets boring quickly, I can't tell why there's some characters you can't cut, and the space you can go is too small.

So uh the whole game is just cutting paper with scissors in a small space? Its kind of ok I guess.

I love how the enemies get cut by the scissors. It's such an interesting flavor to the game. And don't worry about it being a bit empty compared to what you envisioned, we all started somewhere. The most important is to have had fun and learned during the process! I wish for you to do another game jam at some point. Now you know better how to scope the game, and you managed to calibrate yourself depending on your work speed.

Though again, your game idea has potential!
