Thanks for the detailed feedback!
I know exactly what you're talking about with the bottom of the screen being cut off. Some of my other games shipped via nw.js, which is similar to Electron, which the itch.io app uses. Long story short, device scaling throws a wrench in resolution. It's fairly easy to disable, but if I'm honest I didn't think about this game ever running via Electron! I'll see about putting some guards against that in, thanks.
I also see what you mean about the pacing. I had intended for the run-up to the bosses to be a bit of an endurance challenge. The Goth can probably go forever though, provided you find a way to occasionally recover MP (like the Swamp Blessing). I do promise it's not a troll though. But given the tone of the game, I totally see how someone could think that! The endgame should trigger at around 330 exp.
Thanks again for playing! At some point I may take another look at the pacing, especially in the run-up to the endgame. You know, amusingly, I was actually worried it was too short and have been trying to think of ways to go beyond level 5 without breaking things. I guess I read that one wrong.
