Neat game!
The graphics and sound come together nicely for a simple, retro feel. The gameplay is not too complicated, with some fun arcade action. I thought the controls were generally fine, especially after I figured out that I could hit down to fall faster. It would be nice if you moved a little faster than the cakes though, so there's a chance of catching up with them if they get past you.
It looks like your spikes have artifacts from texture wrapping, so that a line of pixels appears on the side with the tip. Not sure what this was made in, but if there's a "wrap mode" setting of some kind that could be changed to "clamp", maybe that would help?
