I really like to concept of this game, it's like minesweeper and picross, two games I also really like. I tried so hard to get the knack of the puzzle but unfortunately it didn't click with me. I think that with a tutorial and a visual guide I would get it straight away and play it for hours, because this kind of game is right up my alley. I tried different strategies like going from the corners or finding 9's, but nothing seemed to work. In this puzzle, for example, how should I know I got all the brown tiles in the right place? I think I'd also like the ability to choose which tile I'm placing, rather than getting a random one. Please keep going with this game, I really like it a lot!

Ah thanks so much for your feedback! You're right - the banana puzzle is unfair. Good catch. In a more extensive playtest and development cycle that kind of thing would be sussed out, but your screenshot explains it perfectly. As for the random picks, I agree with you - it started out as a different game and I didn't have a time to change to the selection, but I would have. It makes more sense given the way you play to have the player just pick which one they want to place. I def would add a tutorial and a guide, and slowly ramp difficulty. I'm encouraged to try to develop this into a full game. Thanks so much again! :D
