this is everything the ads describes. I don't mind watching ads to advance. the gameplay is very easy to understand. I like the length of a battle. I have yet to spend any money. one of the few games that f2p is possible. it's a great way to pass time. I've played other backpack games and this has been the best one so far!

I actually hate tower defense games but this one has a merge aspect that intrigued me. I am happy to report that this game is really fun. Each wave you are choosing your weapons, defense, monetary rewards and so on by merging matching pieces in your backpack. There is the option to get stronger rewards by watching an ad but so far, I haven't needed to do that. I will update if this changes later on. But for now, this is a 4 star game!

Just from lv 1 I can tell what kind of game this is. even with watching all of the ads for getting more weapons still get destroyed instantly by a boss that after replaying the lv he dosen't even show up, obviously your first try is a forced lose. then after winning get buried under a flood of gimmick features that distract you from the core backpack game but forced to do them to get strong enough to beat the lvs. same as all the others. dopamine gimmicks and advertisements galore.
