Regarding the enemies, my plan was to have the slimes be hard at first then stop being hard once the player got some more die faces with higher damage. That's part of why the chest early on has a really good die face in it. Unfortunately I had to keep reusing the same enemies with more health because of running out of time before I could finish coding the other ones.
I am currently working on a windows port for people who aren't comfortable using emulators. Other than that I'll wait to see how many people actually play the game before deciding on whether to make more versions.
Oh, and thanks for playing.
