I'm happy you enjoy the game. The game is 'pay what you like' to accommodate the physical sales but you won't be able to see the downloads if you don't pay, or if you pay less than $4. If you'd like to purchase a physical copy, I will have more for sale in the future, probably mid-2023. The small profit from ROM downloads and the first run helps me produce the next batch of cartridges and put a little bit towards producing my next Game Boy game.
