I've been playing the game since launch, and overall it's a fun game. However, having re-buy VIP every 30 days is dumb. Also, the enemies start getting hard to kill very quickly. A very slow grind which is annoying. Overall, the events in the game are fun and interesting, but having a time limit per level is frustrating. You can hold off the enemies, but run out of time and you lose. Very frustrating. All in all, decent game, but needs some optimization.

Enough with the forced tutorials. Especially if you're going to scale the mobs way up to the point where they're practically unkillable, the gamer needs a chance to customize their loadout. Everybody's played this game before under a bunch of different names. We already know our way around. Tutorial needs to be skippable. Game seems like it will be fun after the long, forced tutorial. Starting at a 1-star, because of the complete lack of consideration for the gaming experience at the start.

Hello! Thank you for sharing your thoughts. We understand that the mandatory tutorial can feel long, especially for players already familiar with this genre. Your feedback about adding a skip option and improving the early experience is valuable, and we’ll review it for future updates. Thank you for your helpful input.

I've enjoyed this game so far. It has fun gameplay with unlockable "towers" with a card system that makes them stronger. All ads are optional. After 2-3 days of playing I have not had 1 ad that I didn't ask for. Progress seems steady and I don't feel like I've hit any limiting walls. I have seen other reviews talk about mandatory tutorials but they must have been very short because I remember playing the game more than getting through a tutorial.
