I got a bug. Went to the level select screen, and one of the level buttons (the next one I unlocked) blew up to a big size, and then I couldn't click anything.
Hmm, just got a chest puzzle where I needed four blues, there were five on the board, and it was only possible to get three, because the other two weren't anywhere near any others horizontally.
i'm not so much bothered about the map with all the places on it, but the little hp bars would be helpful. also the action bar is ok but it does get a little annoying having to wait so long if you want to play for longer. another thing is that the shopping system could be upgraded so you could buy in bulk instead of having to buy things one by one
