Incredible! What an amazing entry. The art style is fantastic. I loved the sparing use of color against the kind of 1-bit black/white art. I loved the CRT effect. Once I understood why the head bonking mechanic mattered it brought new meaning to the feeling of the jump which felt really nice. I think the difficulty level was nice.
I will say it was a bit heartbreaking to die right before getting your final coin and then having to start all over, but overall this was just a beautiful submission. Great job.
