Look at all the newest reviews that have more than 2 sentences will let you know what you're getting into. Very fun game for the first 10 levels or so, then it becomes either a pay to win, or grinding for over a week to advance. Even if you didn't have to pay for 2x speed, it takes way too long to move up a level. Rewards for the long ads are really bad as well.

Ads are sooo long... and they're back to back. And $50 for no ads?! Ridiculous! The in-game upgrades come so slow, I can't even beat level 5 with a perfect score. LEVEL 5! I would happily deal with the long ads if the game was better balanced. Cool downs are shite and the upgrades are kinda weak. Could be a fun game. And I would consider buying ad-free for a significantly cheaper price.

The game was very addictive for me, which is very nice. I really enjoyed the early progression the difficulty and so on. However, once you pass that initial phase it becomes pay to win. I got stuck on the same level for several days and you simply dont get upgrades or items to continue progressing. Furthermore, the equipment upgrades during the game will many times not favor you, forcing to watch 3(!!) ads or paying to refresh the options. So yeah, fun at first then pay to win
