Very fun! The art style is very cute and made the experience better overall.
Navigating through the map was a bit tricky. There were plenty of clipping issues and misdirection due to the placement of trees, and it took me a few seconds to realize where I needed to go and that I needed to dash through the bushes. The latter should have a simple fix, however, by editing the dialogue options to say something like "Use your Flame Dash to dash through the bushes!"
Another issue I encountered was having to wait for the monsters to come to me in some areas because of the trees, so I'd have to sit a distance away and wait for them to come - or get close to them and risk having them land a free hit on me. It was also hard to see due to the many trees and often times I'd be getting hit by a Sadkarp or Zapbird and would have literally no idea because their sprite would be obscured by the trees.
Speaking of trees, I found constant difficulty in getting the "Hide in a tree" command to work. It's irritatingly tricky for something so simple, but overall not really game-breaking; kind of just annoying.
As everyone else mentioned, the command reactions need to be fixed. A few times when the trainer gave Bompurr a command, I'd be told that I did it wrong before I even saw the text pop up :(
This game is simple and enjoyable, and doesn't outlast it's welcome. I can appreciate the time that went into this game and I think it's super cute for a quick Game Jam submission. Hopefully in the future you'll take these critiques and suggestions and implement them into future games or future updates! You have some real creative potential! :D
