there seems to be an impossible jump near the start - the 3 blocks part - so the game is unplayable ...
Hi bigjus!
The game can be completed.I don't know exactly where you got stuck, but for any problem, you can consult the playthrough that I made.
If I didn't get it wrong, you can't make the jump because you hit your head.
This is because you have to tap the UP ARROW, without holding it.
