This is a super easy kaizo hack pretty much. The design is made in a way that you need perfect timing in jumps to keep up in the level. I must admit that there have been used some creative ideas, like when you need to remove a throw block in order to free a grinder and proceed in a spiked path. Unfortunately, it wasn't too fun overall, since this hack is impossible to clear without abusing savestates.
Aesthetics are okay; the author used vanilla gfx in a good way. Not else to say.
As only issue I found, music breaks on accurate emulators.
Overall, 2/5. It has neat ideas in the design, but it's kinda rageish without savestates.
