Solid game! Had fun playing it, especially once I got to the final boss! Also had good bits of clever design, such as teleporting players to a checkpoint if they fall into acid, instead of having them just bounce in the acid as so many other games do. Only issue I had with it is that it eventually started to drag a bit as it didn't freshen up the levels or introduce new enemies/mechanics for quite awhile. Once you get to the final boss, however, it's all worth it!
