Thanks for you're feedback. Pokémon was actually one inspiration for the battle system.
Attack animations were planned but I figured there was no way for me to get them in the game in time for the game jam, but I should have probably still put in some kind of indicator in hindsight.
There is actually some information about the attacks in the game, though it can be pretty easy to miss. Waiting on the monster info screen for a few seconds changes the info from the stats to attack info. It's something that I'll probably just change so the player can just swap between the different information at will. You are pretty much correct about the attacks though, and most follow that pattern, with a few exceptions.
The eerie static you heard was original supposed to be background ambience, and the only reason I left it in was to give a break from the overworld theme. I might swap it out for a shorter more fitting track at some point since it doesn't quite match well enough with the theming.
I think I know what you mean about the jump, but if you could elaborate on what you mean by that it would be very helpful.
I do find your reaction to the player character's design pretty amusing. It originally came to be when I was planning on what to make for the jam. I feel like it may not be the best fit, but I thought it would work the best in a paper design and couldn't think of anything else at that point.
