@ix: You really need to go through early battles to level up for later ones. A battle tip is to jump from far away and do the Jump attack, or to dash. On the other hand, I didn't thoroughly test the difficulty (only a handful of playthroughs for certain rooms). I also didn't have time for multiple difficulty options.
@dalbinblue: There is some weird glitch that I can't figure out that puts the player in a random battle against red guards. It only happens in the very beginning of the game too. If you jump behind them, then they can't counter.
@epiplon: I still need to practice some quicker character/animation spriting for 16X24 and 16X32. Though if I had the time, I should have done a 200% screen option.
@ghostmaple: Thank you so much! I'll change the game file so it's an exe (soon). I'm not new to GM, but this was the first time I compiled an exe for windows in GMS.
I accept all suggestions even if I don't acknowledge each specific one. In some cases, I've already thought of the suggestion (skip intro, major improvements on counter system, etc.) before you suggested it, so that's why I might not reference it.
