Managed to make it to the end on my second try! Getting a good handle on the effect mechanic helped a lot. Overall this is a pretty solid base for a battle system with figuring out the ideal attack loadout under a time limit, and I'd kind of like seeing a whole adventure built around it. If I could suggest some changes, it might be more engaging is if it was less obvious what the enemies were weak to (like if there were other cues to an enemy being grass type besides it just being green). I also feel like the "defend" mechanic could be a little different, though I don't really have any specific suggestions. The in-battle music was also kind of unfitting. Otherwise, good job.
