it isn't exactly a bad bug, just when you hold two of the same potion in each use slot you can use them infinity, i assume it has to do with the fact that in each stack it counts it as having two ready, so when you use only one stack the other overwrites the value so it stays at 2

side note, it does get annoying when there are areas/doors/monsters that are out of reach which makes it difficult, as well how easy it is in some areas to go out of bounds with no clear way to return

Whoa, did not know about the double potion thing! It will sure get fixed on the next update.

About the out of reach areas, this is a legacy from our metroidvania phase. We will make sure to improve the level design as much as we can to avoid this kind of frustrations.

Thanks for the messages!
