Septenary

Thanks, I tried it again and found it engaging, but sorry it is not the game for me. There seems to be a best strategy, but I don't take the time to figure it out and try over. Instead of reaching a level of gameplay frustration and determination to go crazy and try many times to accomplish a level, I do not feel motivated. I believe others will be. The game '10' and sequels, surprised you don't know what they are. Your game seems inspired by that type of puzzle and a little bit of 2048ish. 10 really has a hook. If you get any badges, I'll probably have to try your game again. Thank you for improving the tutorial so I could understand what I was supposed to do. I was actually doing it wrong and still succeeding.

I'm not sure I understand the goal. I'm just clicking numbers but I don't understand why that increases the number and it's not interesting, should I go further maybe I would but I don't want to.

Don't get me wrong, I think you have a good puzzle game going here. But the work seems... unpolished. It looks more like a student project than an aspiring game. But that doesn't mean you can't get a finished look in your game. I mean, take 10 for example (it's a game on this site). The game itself is very simple, almost as simple as yours. But the artwork, the music, it all adds up to educe a certain feeling. Now you could make that sort of feeling in this game as well. All you need to do is polish up the buttons, the UI and the sound effects a bit. But make it original. I can't rate you higher than a 3 for pure gameplay, but if you try to make it polished, I will definitely raise my rating. I suggest looking at other puzzle games and analyzing how they try and use artwork to achieve a certain wow factor with players.
