Gameplay is great

Once you get the hang of it, this game is super fun. The daily puzzles are a great reason to keep coming back, and it’s nice that if you play enough, you can miss a day or two and keep your streak.
The text in some places could use some work as the font seems to not load sometimes, though.

Flawed

I so badly want to give this game 5 stars but it has some glaringly obvious flaws.
1) it’s almost impossible to play in the battle arena given the short time that it’s available.
2) people cheat to get high scores in the daily challenge, and it ruins the fun of playing it. It is literally impossible to beat the hard daily challenge in less than 10 seconds unless you are cheating. Shocked the devs haven’t stepped in to solve this.
3) there should be more you can do with the stars you earn.. it makes them sort of pointless to collect.

If the devs fixed these issues, then this would be one of the best games in the App Store.
