The vibe is really good, even the menu feels good and responsive!
And: Thank you sooo much for making it possible to change the controls, that is so important, especially with tetris type games!
I like the idea and its fun to play. I especially like the fact that the border warps from left to right so you can cut the block in half.
There is just one thing i am wondering: while the nudge idea is really unusual and clever, for me it was more of a nuissance since i played with sort of a 'fire and forget' method , but when a couple of blocks are en route, its easy to bump into them and misalign them. The fact that all blocks accelerate when you send a new one makes these manoeuvres even more tricky. I actually avoided the nudge the best i could since the reward does not really seem to outweigh the risk of losing the game. But, then again, maybe thats just my skill issue :D
You could maybe add a beginner mode where the blocks fall as you send them without being nudgeable?
One more detail i noticed: it is a bit tricky to get out of a cramped space, you have to jump and then right for example to slip out of it, maybe you could make that move a little more forgiving.
Overall, great and polished game - congratulations!
