Thanks! Yeah, looking back I should have capped it. I realized it too late to have time to adjust the level as well unfortunately. But trying other platformers from the jam really made me realized that it falls way too fast and that the frame to jump on the circles is very unforgiving even as I increased the hit-box mid jam ( thought it was just making it more challenging but it quickly gets out of hand as you say. I had watched GameMaker's video on platformer physics and wanted to avoid the floaty feeling, but went too hard on the other side!
But I am happy that you enjoyed the look and feel, because I spent a few days just fighting the lighting system and trying to remember the GLSL lessons I got a year ago!
