I don't know for sure if this is where I should write this, and do tell me if I should write somewhere else, but some bugs and typos;
When using an item (at least with Mushroom Ointment) it'll say, "Your CM Reduced by a 20%!"
Jumping overall is pretty finicky, at least in visuals; the log hopping at the waterfall for example, although perhaps not too replicable, I was able to jump from the first two logs, and then they began to move when I jumped to the third, so it looked as though I was Jesus standing on water (forgot to take a screenshot). What is replicable is jumping over trees and such, where in the forest, if you go to a tree, and try to jump over it side ways, you will jump over it.
Setting your name doesn't do anything to the sign outside your house; I set my name to "DrWeeb" and the sign's name still read "Deck"
The winged boots tell you that you can "dash" but the hole in the wall reads that if you could "slide."
When loading the game (just launching) spamming Z and X, you might open up the menu for whatever reason. Don't know if this is a common bug of RPGM.
In the same map, near the bottom right, you can jump into the trees, and down the cliff. At the flower, you just need to walk, and you can go down.
Yes, most of these are minor. Still thought it was worth sharing.
The most important thing to fix is the jumping.
