Minigames were pretty good, and I like the setup!
As others have mentioned, the title screen can be harsh on the eyes. However, what's worse is that since it is a rapid repeating pattern and alternating color, it could be very dangerous for anyone with Epilepsy.
I see you're going to work on changing that after the jam, so no worries, but keep in mind in the future you should always avoid rapidly repeating patterns and colors to prevent your game from potentially causing someone to have an actual (and dangerous) seizure.
