Solid not too many forced ads

Terrible tower defense slop

dont get this bs 🇮🇱🇮🇱

Needs a re-work/bug fix

Other reviews are wrong in a way, while it is tough to win, if you employ the right strategies you can pull back to back wins semi consistently and when you win you don’t get an ad. Nonetheless what needs fixed is when you drop pieces in between the starting platforms they have a chance to wiggle out of place and be crooked when there’s nothing you could do about it. The reason I brought up a re-work is because the game would benefit heavily from snap movement like classic Tetris as it would guarantee your start wouldn’t get ruined and you can still get punished by the physics of the game causing pieces/whole tower to lean and fall. Also, what other reviewers failed to realize is the game is RNG based to a degree so you can’t just expect a win if you think you’re playing good

In app purchases and ads

This game is great but the fact I can’t make in app purchases or even watch ads to get 2x speed is annoying if that was fixed definitely worth a 5* review
