Thanks! In the full game there will definitely be more of an introduction to the mechanics; since the demo is really short/easy once you figure out the twist, I left it to the player to learn from trial/error to sort of extend the demo's longevity. There's the Tanuki Tip that mentions defense but I think that's a little further into the island.
Definitely have a lot of enemy variation planned once you get off the demo island!
This game would never have been possible without this asset pack so I really appreciate you giving it a try!
