Overall great game, the only ads are optional. My only negative thing to say about the game isn't even a huge deal, just bothers me. Red blips, if I open the shop or boosters or whatever and see the item it lets me watch an ad to receive but don't watch the ad yet, and click a different screen the red blip stays there. I hate red blips being on the game with no way to remove them other than watching all ads every day.

playing on an android s23, game lost memory reloading a run well into 300, lost 90% of the things costing gas, any supplies used was unusable (totals did not match) lastly its really easy to max out major upgrades fast by 300. Game becomes a battery munch for little reward currently. Good to play for a week than move on currently, Ad's completely optional keeps it at a 3.

I had my review at 5 stars, but as many others have stated, at high wave levels the frame rate drops DRASTICALLY. making the game almost unplayable. They could help with frame rate if they have an option to remove the hit point counter on enemies. Also a new map with different visuals, but for me really it's the frame rate drop, please fix this. Removing the hit counter on enemies really would help with this situation.

From Wave 201 onward, a harsh challenge awaits.

(All rewards accumulated so far will be granted, regardless of your choice.)
