Graphics were good the interface and menus were clean and presentable. The backgrounds were sufficient not spectacular, just grass sky and clouds basically. I enjoyed the 8-bit style. It wasn't very animation heavy but I don't think it was necessary anyway so what you had looked right and was done tastefully. Nice touch on the bloody death on the spikes.
The audio was good sound fx were done right with the light sound for his bounce and the sounds for when he picks up the orbs. I also enjoyed the cheesy audio recordings for when you die. The music was simple and catchy would've nice to have an alternate tune because hearing the same loop over and over can get old after a while.
The gameplay was done well it's something unique. Nicely designed levels you used the platforms and spike traps creatively. You also gave a nice steady introduction to the gameplay in the first 3 levels. Overall I feel like I had good control over my character, it begins to feel natural after you get through a few levels. The game was challenging but not frustrating which is about where it should be.
Overall the good game probably not something I'll come back to but good enough to make me want to see it through to the end.
