At first I though the game is hard, but then I realized stats upgrading is a thing (yes I didn't check the gifs, fight me)
Update (With spoilers ahead): after completing the game on a good ending (letting Timmy leave by himself) and then remembering that if you upgrade everything you can leave to the afterlife, I got the best (and what I believe, the true) ending, the game was totally a blast, and it was a bit silly one-tapping every enemy after upgrading my damage to the brim at the very beginning. Amazing and wholesome, really enjoyed playing it!
