A nice concept! Took a bit long to long (downloadable version), but i think that my slow PC's problem... But a very fun game :)

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!

That's a lot of work in visuals and music, it's nice

but I couldn't get any coins and after killing the boss and clearing everything - there was no end and no way to die.

also doors lead to the wrong places sometimes. Confusing

But with this fixes, I think it will be a great game!

visuals and audio are great, the game design isnt quite there. Spawns are a serious problem, shop mechanic is great idea though i never got a chance to use it as i was given so many bad spawns and died instantly.

Awesome art and music! The only problem is that as soon as you enter a room you're instantly surrounded by many enemies before you can even look at what's going on, you should've added some sort of cooldown for enemy activation, or at least let the player prepare for what's coming. Also being able to shoot without cooldown is a bit overpowered, but overall very nice game!
