I found the hand drawing really cute. Not much of a game there aside from that though! I was able to finish it in a couple of minutes (aside from the first training which I rage quit due to not being able to time the space correctly)
I would try and look into that because it felt like something was wrong with the timing, and also i would personally let the player manually start each training after being displayed the intro popup. As it is, I did not have enough time to read through it before it disappeared
