This is, a really good game!
The gameplay is a combination of a platform, and puzzle game. Besides avoiding spikes and making precise moves and jumps that need to be timed, you also need to think about the layout of the map, and what route you should go. I like that concept, it works amazing in this game!
The graphics are also good, they're retro, simple, and have a distinct contrast between monochrome backgrounds and colorful obstacles. The combination of these characteristics, make the visuals of this game pleasant to look at.
The only thing that I found lacking, is music. A game like this, would definitely benefit from having some kind of chiptune music; in my opinion, it would make this game a lot better!
But even then, this is a solid game, which is really fun to play, and deserves a good rating!
