5⭐️ game! It is very complicated at least for me figuring everything out, and there is a lot. But it is still a great game. I get no forced ads and there are many options for the games. Theres just normal, then ranked, multiplayer and events. I found this game challenging for sure, but I like that it is(or I am just bad at it lol). Large variety with weapons, skins, and things that power you up like clothes, rings, etc. I definitely suggest downloading this game! Monsters look kinda goofy lol :p

Thank you so much for the awesome review! We're glad you're enjoying the variety and challenge—even if it feels a bit complex at first. No forced ads, lots of game modes, and goofy monsters are all part of the fun! We'll keep working to make things smoother and even more enjoyable.

please reset the scores for the apocalypse dungeon. the scoring is different, and the high scores are no longer relevant. stop using the co-op dungeon as a mission quest, or in general since it rarely gets used. cool name, but it means you can't see the screen when in sunlight. tower placement can be very frustrating when the tower jumps 1 space when you release your finger. please do something about the endless dungeon. unplayable after 24 minutes. graphics settings have no effect.

update down to 2* from 3. unplayable at higher levels. less than 1 frame per second. additionally, some things don't work as text suggests. for example, Living Tower hero at level 3 gets "one of each equipped tower at start of game" and this has never happened (and is why I focused on getting this hero, so a big let down). please fix things because the game was fun when I could play.
