Use the arrow keys to move, and Z to select. As you can see, this is far from being finished, so don't complain things like "It's broken" or "Bad." I need testers and people to give suggestions.
Obviously, a lot of inspiration from Undertale. Code is 99.999% by me. (Exception: I was having trouble with the box collision, so I went to Hobson-TV's Undertale project, saw the code, and coded it in mine. It didn't work, so I edited it so much it's not really recognizable.) Art is 80% me. I did the player, backdrop, particles, watermelon particles, hit board, hit, icons, and Scratch cat. The rest is from the library, converted to bitmap. Sound is "Hero" by Shady Cicada.
