Really? Pay to complete events? pay to win all over the place, no. Re: I am not paying to go further than a few steps into the puzzle event, nor several steps after. A purchase should not be for individual levels, it should be a pass a separate tier. Locking progression until you get the last one is absurd too. It's locked at level 5 and the only way to progress is spend $0.99, THEN I see I head that levels 13, 21, and 30 all also have their own separate charge.

I only have two problems with this game, you eventually get to a point where you're having to watch ads to obtain enough gold for upgrades and the Tourney events take too long to lose. My current run is over wave 2000 and I'm nowhere close to losing and it's been an hour and a half. I have had it happen before where my tourney run was so long I lost after the event was over and received no rewards.

It's a pretty fun game but it certainly has concerning flaws. I'm playing purely f2p and making steady-ish progression which is only possible by watching a bazillion ads. HUGE issue with your stats and bonuses rolling back. It's like two steps forward and one step back... extremely discouraging. If this ever gets fixed I'll redownload and reassess. Too bad the game is really fun outside of that.
