Another game with hand-drawn art style ;) I thought it was really cute, I like the dango looking slime ball you play. The modes were a ton of fun and the platforming was at a good challenging level, with varied designs utilizing each mode. The music change is also a nice touch.
I think my biggest gripe is the aim indicator, having it on mouse is OK but the fact that you can't see the cursor makes things harder. I think most people are used to a crosshair or something on the cursor, or even just letting you see the indicator in all modes would help. Going from yellow to green/red while midair means I usually have to flick to where I need to aim. Other than that this is a well-made game, nice job!
