This is a difficult game, but great. Of course, you will die a lot. But you get stronger and better the more you play. As you level up, you get permanent upgrades and new gear and weapons. At first, you might not make it past stage 11 of world 2, for example. But the more you play, the next thing you know you're beating the whole world. The game has worlds for each level. Each world has 30 levels (so far I'm in world 3), and if you die during any of the levels in that world, you start again at level 1 in that world. But because of the level of yourself and the equipment and weapons you encounter each time, you will progress further and further with each race. I love the game And there are no ads unless you choose to watch a video on certain levels that don't have enemies, to get a random boost. In these non-enemy levels, there is also an angel who will heal you, and every few levels you can choose one of three boosts. Definitely worth a try (pun intended). I downloaded this game by accident and I'm glad I did. I decided to play before deleting the app and I'm glad I did that too. It's a quick time killer. You don't have to wait to complete tasks and it never ends until now. Great game to kill time on appointments while waiting to be attended... as long as you have WiFi connection or unlimited data. This game will definitely get you a $1000 dollar phone bill with no WiFi connection or unlimited. Can't wait to see new updates. I wish there were more active promo codes to keep people interested in continuing to play. This game is very addictive and has been playing for a while. It's too simple but challenging and too skill-based for a mobile game with "rogue" performance. Once you get the hang of the perks and upgrades, it becomes a much more enjoyable experience. I would really like to see some more updates that can add a way to pay for not having to wait for your energy to recharge after just a few games, and more interesting and cool perks to use. I'm more than willing to spend a little money on this game, especially if I don't have to wait a few hours to play. I love this game. But it's very difficult to cross each world. It takes a long time. It would be better if after winning the first 10 rooms, from there you start in room 10 as a checkpoint. And the same for room 20 as a checkpoint. Because playing all 30 rooms at a time is a drag. It's one of the few I play on a daily basis. The others are a word game and a puzzle game. I even have a controller that clips my phone to it and I can tap it so I can see the entire screen and no finger smudges.
