The problem is that the game will likely not receive the changes and fixes it desperately needs. You can look up the other games they made. All of them (except maybe Locket and Pains) are unfinished and abandoned. The mobile version for pacman game doesn't even work.
Hey, it hasn't been THAT long since this game's creation, not to mention I've been promised by the developer themself for a significant update soon. I'm sure this game is its developer's most ambitious project to date, as their previous ones (in a positive light) can be viewed as testing waters and practice in game development. I shall remain hopeful no matter what you think.
