Do not purchase! I purchased both the unlock and the remove-ads options in July.. Both purchases went away in October, after I had done about 200 puzzles (including the free ones). When I went to document the purchases for the developer, I found that I had previously purchased both unlock and remove-ads in 2019. Apparently the same thing happened to me then, and i had forgotten two years later. The developer responded by suggesting I purchase again, and if charged (which I obviously would be) he would refund me - and what next? Repurchase and again refund, every few months? This is not a vital game. Futoshiki is a nice alternative to those in the (free) Simon Tatham puzzle packages, but I can get along without it, and there are a half dozen different Futoshiki apps I haven't tried yet. Play the sample games, easily worth a couple of stars, but pass up on the purchase opportunities. Puzzles are supposed to be fun. This isn't.

Overheats phone in less than 1 minute, 😭😭. If it wasn't for that problem I would have rated it 4 stars. Would give 5 stars if there was an option to save checkpoint. Love the current controls and layout. Btw I only played off line because I don't have wifi at my house, not sure if that is a factor in the overheating. Never had this happen before. Will uninstall for now. **Still overheats takes 2.5 min now

Hi, Sorry for the overheating issue. It is fixed now. Please reinstall and check if the fix works for you. If you explain the details of save-checkpoint feature that you mentioned, I am sure I can implement it. Again sorry for the inconvenience.

Love the game. The hard fill buttons are too close to the pencil fill buttons. It is easy to hit the wrong one by mistake resulting in the error warning and point deduction. I'd suggest putting one at top of board and other below. Also the error highlights things too quickly (i.e. immediately).Better to let game flow and let players find errors as they go. I'd also like to see a "clear board" key as well as a backspace. I haven't paid yet to open all levels and remove adds but probably will.
