I had to drop my rating to 2 stars, it does function with few bugs, but most levels are nearly impossible after 50 without spending thousands in gold, which ends up pointless when one enemy gets by in the 24th round. Now the items and gold are gone and you still missed 3 stars. Even watching youtube guides shows that it depends on extremely specific placement, shot timing, and lucky crits.

It's a perfectly fine tower defense game for the first fifteen or so levels. After that, you'll have upgraded all of your towers to maximum, so there's no way to get more power. There's no way to increase your starting budget, so you have the same amount of money to buy towers with. But there's still HUNDREDS of levels remaining. The pointless grind is overwhelming.

its a fun game but really struggling to get through level 4 I think the only way to pass is to watch an ad so you get 5 more gold every time you destroy a tree literally 1 car when through my defense at wave 13 or 14 and the next level i defeated all of them I maded out the turrets that I can use during the level 4 . I am disappointed
