The graphics are cute and catchy, really liked that.
I don't understand why you need Z to open the dialog box and C to close it, why not putting on the same key? Having too much keys to press on was a bit overwhelming. Also I thought that putting W as a jump key would rather be more comfortable, but that's my taste :)
Also collision boxes were a bit hazardous as sometimes my character was "bumping" from corners. There was no grace periods at the edge of platforms which was a bit frustrating. The camera movement were a bit hectic. And I don't know if that's normal but at some point I couldn't draw anymore.
I thought I used too much drawing, so I playd the game with minimum drawing in case there was a limit. But even that at some point I couldn't draw unfortunately. Don't know i that's normal ? It often happens when you respawn.
Also I liked that when you die you don't loose your drawings, that was nice :)
The music was discret but enjoyable and I didn't hear any sound fx. But well done on your entry, that's a cute little game you have here.
