Thank you for playing! I'm very happy you liked it!
It is indeed quite hard to play the way I envisioned it, and probably the way you have played (keyboard alone). Some folks on the DR discord found a way to cheese it using the mouse and the left and right arrow keys. Playing on the smartphone is also easier XD.
I beat it on keyboard some times, but after I started to cheese it I just can't bring myself to uncheese it XD
... Now I kinda want to make an achievement system and add an "keyboard only" category XD
