This isn't much of a game. It just feels like someone started tinkering around in Unity for the first time and completed a beginners tutorial. Why someone would charge money for this is beyond my comprehension.
There is just 1 simple level with 4 platforms where up to 3 enemies spawn in from the sky and they either go left or right - following the exact same path until they fall into a hole at the bottom and respawn again. The enemies spawn in with random speeds and hit points, but it is essentially the same thing over and over. All you do is jump over them and collect orbs to level up or shoot enemies to get points to purchase skins. The skins do nothing and leveling up just makes the bullets do slightly more damage, but the gun is almost pointless anyway as it's just easier to jump over them or avoid them since they are very predictable.
If that wasn't bad enough the achievements take forever to get. The orbs needed to level up grow exponentially so to get to level 10 you have to collect for hours.
