I really loved the art style of this game, as well as the chiptune(?) music it rocked throughout. The look of it gave me massive OFF vibes, whether intentional or not. I was intrigued about the story and what was going on, and I liked how you gained new abilities by finding them out in the wild.
I do wish there were more enemy variants, though. I'm also not sure if there was any poison resistances I could pick up anywhere (if I did I didn't find it, which is on me), but I wound up developing a burning hatred for those poison slimes at one point or another, haha. If there isn't any poison resistances, then I'd suggest lowering the odds of the slimes poisoning you, as I wound up having to backtrack to heal at the shrine quite often because of them.
Also, while playing, I ended up getting an error and had the game crash because of it. I'm not sure why, but I thought I should share it so you were aware. IT read "Script 'RME' line 1364: NoMethodError occurred.
undefined method 'flash' for nil:NilClass.
Overall, this game was quite charming, and I liked the aesthetic that you were going for with it. Well done!
