I loved the variety in this game, it was awesome to see different levels and music for each playthrough, so that was a great use of the limitation! The main gameplay was also great, I loved the fact each dungeon was different, and the different hats really added to the replayability too, so that was a good feature to have added! The only bug I encountered was that if you clicked fast enough (i.e. fast enough to make your finger hurt) then you could shoot the boss out of bounds, softlocking you since it couldn't be killed - though that's less of a problem of the game than it is of my desire to shoot lots of bullets! Besides, I loved the graphics, particularly how the colour palette changed from nightmare to normal, and the menu art was very well done too - it gave the game personality - so nice work on that! It was a fun game overall, so good job on making it!
