The game is good but,...
there are some issues I have with it, namely strange bugs and glitches.
First of all the random generation of the map. After you generate a new map the key and some map icons are spread throughout the entire map, sometimes even outside the map. I don't know if it's intentional but if it isn't look it up.
Second if you just barely move in a room that triggers mob spawning and locks you in and you press down and there is a map under you, you magically teleport to that room. When you go back in the mob room the event triggers as normal.
And third the ending. I made a cursed ring but I either get the bad ending(didn't save her) or a black screen of doom and after timer runs out game over.
If you fix those issues the game will be great.
That's the reason I'm giving it 9/10 4/5.
But overall a good game.
