It's bad. Pick O to win. You might need to use I if there's a staircase. If you do that, you can't lose. Sometimes the level is design stops the enemy from progressing. The bounce pads and balls that knock you back, which doesn't add difficulty. You never lose, so it's just aggravating. If you can lose, it'll be because you just got unlucky. Each match is 20 seconds at most, and at the end of each there's an ad (to many). Great concept. Could be 5 stars with work and less ads, but not right now.

Awesome game except for too many ads 😀 Very entertaining also

This game is barebones, to say the least. Using X can net you a win everytime, as it scales and performs all obstacles exceptionally, but you won't even want to play this game because of the in-your-face advertising and awful visuals. The thing that makes this worse is that the concept is fairly unique and makes way for some pretty interesting level design. I would LOVE to see it someday, but for now we are left with this shamefully wasted opportunity.
