Rather cute game at its core with simple yet most certainly workable mechanics. The custom voiceovers do add to the charm of the game, but it would be nice to not have to deal with the ghost each time I play the game again. The ui is underdeveloped but the assets obtained for the game do produce a rather consistent style.
One thing that might help that I can provide right away could reduce your tiles tearing, go into edit > project settings > quality then turn antialiasing off it might reduce the flicker that seems to happen on the edges of your tiles.
