This is a solid game. The controls feel snappy and responsive, the level design is excellent, and the pixel art is gorgeous. The only feedback Is about the spike traps. In the earlier levels you establish a rule with your players that spikes only kill when you land on them, meaning you can walk through the spikes if you want to. Once this rule is established players will make their "plan of attack" so to speak, with this rule in mind. but in the later levels you break that rule by having the spikes kill even when you walk through them. When this happens the players feel as though they played by the rules but the game cheated them which is not a good thing. If you want to have spikes that kill both when you walk through them and when you land on them then make sure you make it very clear it is a different type of trap from the spikes. Other than this very small nitpick I had this is a great game. Sorry for the paragraph :P
