wow, was not expecting something like this for a jam. I really wonder how you managed to make this. It's very easy to get started and you get it immediately basically. Very unique and there are many ways to work on this. I'll try to say something other's have not yet, and that is I think if you wanted to you could make it so there are different missions or criteria that you have to complete. Like optional challenges of creathing levels with a set amount of enemis or something. JNust a thought. Good job man esp since this is youur first game jam.
