Its a nice game, although there is a really easy method that i found that just rushes through all of the codes, all u do is just start at 5-5-5-5-5 and then just follow the +'s and -'s, which kind of kills all the puzzle elements of the game, but for a game jam its a great game! If you ever wanna come back to this project and improve it, maybe add some more puzzle mechanics, or add so you can't put in 2 repetitive numbers, those are just some of the ideas. Good Job on the game jam!
