Oh, this was super cute! You did a really nice job, it's short but surprisingly well polished for a jam game! The art is all very good and I like a lot of the effects and little touches that show how much passion you put into this. I like the momentum based struggle system; I haven't seen that in a vore game before and the rhythm of it is neat. Ending's very cute and sweet.
My one big critique is at that the mountain climb at the end of part 2 - the first jump after a spawn crystal (checkpoint frequency 2) expects you to use running momentum when you hit the ramp up to get slightly more height. This is fine on Control Mode A where you simply add the second button, but extremely difficult on control Mode B, because the tiny button release on an upward ramp kills just enough momentum, and you lose the boost you need to make the jump. I had to switch to Mode A and play on keyboard for just that part and was able to switch back to controller after it was clear.
Otherwise, this was a really fun little play! Thanks for making this! <3
