a review says there's no undo button. any plans to add one?

Does this game actually get dev support or was it a slap it up game and leave it be? No one has responded to a single question. I don't want to buy a game that doesn't have support.

On launch i can hear music but am faced with a black screen and the odd flicker of the main menu screen, i have to close the game via task manager, is there a solution to this?

add if want, expire 7/24

I've noticed that none of the 'Right' facing arrows (down and to the right I guess technically) push the character off the arrow. Every other arrow in the game automatically pushes you off of it, and the right arrows do prevent you from going any direction other than right, but force you to do that movement yourself. Not a huge bug, nor is it gamebreaking, but I thought I'd make sure it was known....
