5 stars: Good game. Would recommend. I've completed all puzzles. The write ups are cute and interesting, although some need to be proofread. Controls can be a bit finicky, but you have multiple options and overall good. Three layer ads, but not terrible. Overall, a pretty solid game with a couple minor issues. Compared to others, it's a very solid, well made game.
4 stars: I really like this game and I love all the facts, but when you get to 20x20 the board is so small I often misclick a lot of the time and zooming in isn't useful for bigger numbers. It really ruins the whole experience when I accidentally fill in ones I didn't mean to. My suggestion is, a mode/pen you can easily switch to. You fill in the spots you need, and it tells you how many it will fill in and only after you press
3 stars: It's fun and all... But it'd be better if there wasn't an ad in between every single puzzles once you reach the 15x15. Plus it's those annoying ones where you need to press 3 times on the smallest arrows or x in the universe.
2 stars: Would be great except for the malicious placement of the controls- despite there being plenty of space for them to be higher up on the screen, the direction arrows are so close to the ads that even when cautious, you end up triggering an ad to open every time you use the down arrow. Please fix!
