On the priest's feather/wings upgrade, you say "Save your from falling" instead of "Save yourself from falling"
The level of difficultly is quite nice but I feel the addition of checkpoints would have made the game a lot better. Even if this means making the later levels a little bit harder.
I often found myself falling into holes due to laggy controls (especially with all those trees).
Also, whenever I got a new character, I would have enough money to buy out all of the skills the character had already.
I liked the fact that shops had random items in them, but this system would be waaay better if it was remodelled as the system for big chests. Instead, remake shops as actual shops where I can trade coins for items etc.
