I thought it had a lot of good challenges throughout, but there were a couple of problems. First the beginning was a little bland, it could of used a little music or ambience. Second, There were two or three places I found were you could become trapped and would have to kill yourself, most of which were in that hall where you have to flip the lever to lower the water level. Otherwise though I liked it. It was fun and fairly challenging. Keep up the good work!
BTW liked the endless pit of doom
