This looks awesome, but I have some concerns about that level being unfairly abusing invisible traps >.<. Is it because the game focuses on the player memorizing where spikes are? Because if that's not the case then it might be better to make it so when you are right next to the spike location, a small hint is given about the presence of the spike. Eg if you walk on platforms the part below you could change to a darker gray until you jump or move to the next block, but when next to an invisible spike maybe the platform could turn into a slightly red-ish gray tone?

Aaah ok, it would have sucked if the first levels or so required at least 20 retries until you finally find all the invisible spikes to avoid one by one


Also level themes would be cool. For example, World 1 could be grass + sky as default color set, world 2 the current colors, world 3 some fire place, etc. A level editor would definitively be great too
