Heart Star 9+

This game is really adorable! Everything from the characters to even the music. Levels are nice and short, making them perfect for a couple of quick games. The menus are very easy to navigate (unlike some other mobile games). However, there is one minor issue. When you try to turn off music and sound effects in the options menu, the buttons don't do anything at all. Other than that, this is a must have if you want a game that doesn't take up much space and isn't resource intensive (which is perfect if you have an older device such as an iPhone 7 and don't want it to get too hot).

It's cute and fun. The levels are decently hard most of the time. It's pretty aesthetically pleasing. If you want something to just pass the time with, I would recommend this game. It could be better though.
While it's enjoyable, there's really nothing to be working towards. Just levels upon levels upon levels.w To make it better, I suggest there being more characters to unlock. They could follow themes, and you could switch them whenever you wanted. Every few levels a new one could be gifted to the player. As long as you don't have to watch an ad for it, I think it could be a good solution.
I don't encounter a lot of them, but there are minor glitches that make me have to restart the game. Off of the top of my head, there's one that causes the blocks that you can move to not respond to the character. It sometimes happens when the block falls off of a platform. Another one is when the characters just randomly slide off. I don't know what causes it, but it's agitating.
All in all, I like it, but it could use something to work towards to and bug fixes.
