I Even Pre-Ordered!

I love this game so much! I just have to be really picky on when the time of days when I choose to play it because I get very overwhelmed and my anxiety skyrockets when I play it. I try to practice paying attention more when I play this game too due to have mild to severe Tourettes. Sometimes it gets a bit challenging when my eyes are rapidly blinking but overall the game is very helpful for me when I need a distraction and need to get away from everyone in my bedroom to Tick! Great strategy game! ❤️😊

Quick and Dazzling

The game’s gradual increase in difficulty is great for players of all interest. The graphics are simplistic, which makes the game feel even better and more fluid. The loot mechanic is actually very honest as it presents and updates a graph of drop percentages that adjust based on the items you have earned. Advertisements can get you annoyed at times, but can be brushed out of sight as soon as you start racking up some awesome level streaks. As for the future, I would like to see an updated level cap (beyond 9*++++ or whatever it was). It would also be cool to add a fourth category in customization, like a customizable ripple effect that pops on screen as soon as you score another point. Edit: Actually, the game is endless (so far). Overall, the game is simple and notable. Easy to play, hard to master.

Really Trippy and interesting. There is a minor glitch where the doors moving towards you will stop and you have a second to cheat, but other than that it runs really well. Awesome game and if the developers are reading this, I’d like to help improve the game however I can. I know that the doors stop to change direction at certain levels after level 3 starts but the glitch I was referring to happens every few seconds even in the first two levels.
