I tested both this version and the version on Newgrounds. Great first impressions based on the art so far. I won't bother with an in-depth review/critique since I don't want to cause more harm than good. Here are some noticeable differences between the versions.
Itch.io version lacks the menu and skips the introduction. Also, as the player loads into the game -- the shopkeeper's unlockable scene is automatically unlocked and shown. (Tested this twice to make sure it was consistent).
I look forward to future builds and wish you the best of luck on your development!
