This "2D Rage platformer" definitely delivered the "rage." :-) Unfortunately, I couldn't even make it through the first stage.
But a really interesting, unique idea! Nice art. The rule changing mechanic is great, but I'd love some kind of warning about what the next rule change is going to be. Like, maybe it could show the new rule blinking for 5 seconds before it takes effect? When there's a gravity change, I always seem to be standing in the worst spot. :-)
