You really played it! I did have to rush a few things towards the end, as I had to hit the road halfway through the Jam. If you beat the Ogre, then you won. He drops the Golden Key, but I didn't have time to reflect that on the status screen. There were other keys, spells, equipment, etc. but I didn't have time to implement them.
I'm not sure many who played it got that far, but a big portion of the final dungeon area was created diagonally. Hence the game name. It's hard to keep your bearings in there, and that was the point.
I did have issues with my battle state machine towards the end, but I had to make the submission deadline. Didn't have time to fix it.
Truly, thank you for putting so much effort into your review! I plan on polishing this one up and releasing a post Jam version. Thank you for the feedback!
