Very impressed with how interconnected the level design got towards the end. I sort of expected this to just be a standard linear platformer, but the extra keys and doors and whatnot were really well-done. I ended up with a C rank, but I got the two extra keys and a handful of extra coins.
Some of the laser / buzzsaw cycles were pretty rough to time; lots of waiting around for things to time out, but in the end this was really fun. Great level design and inter-connected map design, nice job!
