This was really fun and challenging to play through. The retro 8 bit aesthetic is really well done here in both the visual and audio aspects.
My only issues were that there were one or two jumps that were pretty tight (1 in level 5 with the velociraptors and level 6 with the logs but that was mainly timing). And during the boss fight I was confused on when/where to hit them. I was waiting on a visual cue of sorts like if it was going to ram into the side of the screen and become stunned. But that last one could just be a me thing.
Great work.
