Thank you very much for the feedback!
I agree with you, the game is too short so we will work to implement more levels.
We tought about adding more jumps, but as a core mechanic it would make things harder to balance. Maybe it can be implemented as a gimmick for future levels?
And my apologizes for the bug with the spikes, I'll fix it ASAP. But its nice to hear that worked in your favor lol.
