I win
Wow is this a small loop for a game over. I think if you want to emphasize that they lost then it should sound a lot more dramatic in the three second time span that you have this written for. This sounds more like a corny loop for a maze of some kind in a game though.
The drums spit fast and sound cool. The synth sounds very cheesy here as well. Not too awful bad though. The bass line is also good. Considering this is only your first audio piece it does not sound too awful bad.
Overall, not bad, I would just suggest making it more dramatic for a game over song.
