This was fun! Loved the little details, zebra removal lol. Could of course have used a little bit more, but focusing on the polished experience was the way to go.
The music worked for all three tracks, but they didn't feel like they fit together very well (three different games, almost). The texture of the main menu track and level track were similar, but the timbres were so different that they felt divorced. I really liked the instrument choices in the level music, consider reusing more instruments across the various tracks to help tie them together. Also, don't be afraid to have more variation in your chord choices for each phrase! Once you've done the same progression twice (I-V-I-V...) it's time to switch it up on the third time! The listener starts tuning out if they hear the same thing three times in a row.
Excellent work everyone!
