Thank you for playing! :)
Getting the controls right certainly was a challenge – and I'm still not happy with it. It's surprisingly tricky: Make them too responsive and it just feels like a regular platformer. But if they are too delayed, it also feels bad because people are used to regular platformers, haha!
It's probably bugged somehow, but at least in theory the idea was that you should get a substantial boost to the impact of your input while changing direction and the (added) impact should diminish the longer you hold the same key. Will look into it later!
