Ridiculous

It’s bad enough you put so ads in this game, which is definitely not necessary, not this many, but you’ve also failed the players by not saving their progress in the challenges when the game decides to glitch and close or a phone call comes in and needs to be answered. It sets you right back to the beginning, all progress lost. It’s ridiculous.

Overheating

The overheating is unacceptable. This is a very simple number puzzle game, yet my phone gets extremely hot after only a short period of playing, and the battery drains unusually fast.

What makes it even more concerning is that the overheating still occurs when playing offline, so this does not seem to be caused only by ads or network activity. A game this simple should not put this much load on a modern smartphone.

Please seriously investigate the app’s CPU/GPU usage, rendering, and background SDK activity. I enjoy the game itself, but the excessive heat and battery drain make it difficult to keep using.

4 adds per game

Good game, unplayable with 4 adds per game… and too expensive “no ads” purchase for what is offered. Milking the player to the max….

Ad infested!

Love the concept, but to be repeatedly interrupted during a single game with ads? No. Deleting it now.

Great game but …

I thought this was one of the best games, challenging and fun. I have no objection to ads between games, but several right in the middle of a game disrupts the flow of thought. Going to delete it now, just too irritating. Another criticism is that the sum of the coloured square is too small for me to see easily. Such a shame, I was really enjoying it.
