oh we havent put this on the app store at all (we dont have the income to do such a thing) though its an idea for the full full version of the game.
also 8 & 9 was meant to be removed due to practically being the same as the first levels we moved them but for some resion i didnt remove them they where made by a friend and i wanted to make things super simple when you boot the game up so they ment to have been scrapped.
Also undo should be working, i havent had any bug reports about tiles not flipping. but i do think there are a few bugs with it though they should should be fixed with an afterjam build when that time comes around (not sure how long it'll be due to the hosts not even bringing up what is going on with the jam). anyways i do really hope you enjoyed my little game (it was made by me LadyLeia by myself)
also if you ever find the name of the game you say is much like ours ill love to know the name of it to see how they developed the mechanics.
