Oh wow 38:13 is an amazing result for golden heights! We spend quite a long time chasing a sub 40 time internally and didnt even know for sure if it was possible before finding 2 rather large skips. Would be curious to see if they are the same ones you took?
The momentum mechanic definitly is a bit oversensitive at the moment, especially when landing jumps and before reaching max momentum. We'll have a look at making a postjam build after we catch up on sleep and the voting is done and hope to make it a bit more consistent.
Thanks for playing the game to such perfection!
