Partial Agreement
I partially agree with Dragonfire187. I did notice in a few spots that my cursor would get hit even when I didn't actually touch anything with the tip. First noticed on the mountain when I'd be squeezing between clouds. Usually on the ends of each cloud is where it would happen. May be of interest to you.
Otherwise, very cute game. The beginning scene kind of reminded me of getting ready to play some Mario game but with cursors. lol. Awesome. I liked having to dodge things that were falling from the sky. Like a mouse-run danmaku or something. That could be interesting... 4/5, 7/10.
