I really enjoyed this! The story and dialog is simple and fun, I love the changing mechanics and it's a very charming short game. Changing RPG enemies to interactable with dialog and not kill you in other modes would fits better I think.
I don't see any use for the "lives" and "game over" since the game will put you back into the last checkpoint regardless.
Other than those I think this game is fun and I enjoyed my time with it to the point I had to drop this game for lunch and pick it back up.
