Interesting concept, but I can't get past the part with the spike moving back and forth between a drop off with two spikes on the bottom right (perhaps number your levels so it's easier to point to a problem).
You're talking about this level ?
It was ment to be a difficult platformer but I'll probably reduce the hitbox size of the moving spikes cause it is sometimes a bit unforgiving, but for this one you just have to find the good timing to fall and then climb back the other side. It'll get even more difficult in the next levels ;)
Thanks for the feedback :)
