Great for original video game music
I had one major objection, but I'll get to that after saying you did good. Video game music ought to give players a hint of direction; you did so wonderfully. You also managed to make a fun little piece that didn't deviate too far from the tone you were trying to set. Your piece was quite obviously original, which is always good.
The objection is this: your parts get too busy and convolted around 0:36 and stay that way till 0:50. There's also a distinct lack of pleasant harmony in that section and instead you've served a minor earful of discord. You may want to reevaluate how many different instruments you introduce or maybe how different their respective parts are. Going too many directions at once takes away the sensation of melody, which can seriously impair the listener's experience. Doubly so with video game music since the player's attention is directed towards the game, not the music(which should serve as a foil for gameplay elements).
Other very minor issues which don't impair the music's enjoyability but could probably be fine tuned:
1. The trumpet part is a bit loud and could have its volume scaled down 2 to 5 percent.
2. At parts the drum section could be construed to be too fast(like around 1:20 e.g.) It's actually OK to slow the drum section intermittently.
3. Don't say "lol" in the author comments, really. If you just stripped out that, it'd be a totally professional statement and make it seem like you're not laughing at your own jokes.
You did good. Happy composing.
