Ads? The maps are far worse than the ads.
Do not waste your time leveling up. The purchasable maps are so awful. I Saved up to buy the "steampunk" style map and its like a bad joke. As is Charon and all the others Ive unlocked hoping to find a fun, fast map to enjoy. Id say the maps resemble the "challenges" which arent challenges at all, just an exercise in pure frustration as one attempts to navigate preposterous obstacles with cheap, unfair rovers. Im a gamer of many years and this isnt "fun" or "challenging" and the higher level content in no way rewards the gamers progress. Skip it.
