I actually really like this madness. I'll rate the effort and the strangeness, the rest's been covered by Overturn.
Doesn't particularly spark any specific mood. Since you stated it's nothing serious, I won't go into the quality of the sounds themselves. When the piano came in at :50 I felt it broke up the song a bit too much. It went from an eerie feel to... "not sure what to feel."
Nonetheless, you have a pretty cool sounding progression. I might suggest sticking with the eerie sound of the synth that comes in at :15 and building around that if that eerie feel is what you are going for.
I felt like the piano with those fast delays helped build around the eeriness. Thought it sounded neat at least, a bit more than a two star :P thanks for listening nonetheless.
Kind of has a eerie vibe but pleasant at the same time. good video game music =) keep it up =)
