I have finished this game now, and this is what I think about it:
The graphics are fantastics, and the game design too. I liked the mechanic of eat an acorn to jump highter, but I didn't like that it wasn't used in the temple. I think that it's really hard to make a side-scroller in Rpg Maker MZ whit only using events, and you did an amazing work about it! There are some bugs with jumps, but honesly, thy didn't bother me much. Finally, I thinkt hat this is a very well-done game!
