Glad you're enjoying the mechanics! I appreciate the feedback on balance, it'll help me tweak it. There is an intentional learning curve with new enemies, and especially bosses, and I designed it with some expected amount of deaths in mind. But if an enemy is feeling annoyingly hard or confusing, that's something that needs changed.
Which boss are you struggling with? Maybe I can offer some tips on how to beat them. Also, if you don't mind grinding for ash, buying some upgrades can help make a fight much easier (using the save points will reset monsters on the maps in case that isn't clear). Thanks for playing and the feedback!
Well, I dunno if it's still early boss or not, But I can't beat the mushroom boss? cz, the area of walkin' is too small for me. well, tonight I want to play it again. (Just thinking a new way to beat it). and yeah, I tried fight each monster in new area, and back to the save point (so I just only beat the boss later) BUT... when I go back. the monsters back too! (Hahahaaaaaah...)
Ah yes. The mushroom mini boss is a definite difficulty spike. I'd suggest moving in the small opening space of the fight kinda slowly, and trying to take out the greenie on the left as quickly as possible, to open up more movement space. The good news is, you'll only have to beat him once. Thanks again for the feedback!
