Difficult but fun! I liked this game a lot once I got the hang of it as it can get pretty chaotic and has a charming art style. My biggest issue would probably be that often, when I was first starting, I wouldn't be able to completely move an obstacle up/down as my mouse would encounter the top/bottom of my screen (which, the comment below me mentions). Outside of that, which was more of a nuisance that I could overcome anyways, this was fun. Good work!
