Had fun, the difficulty is at the right spot.
The zoom-out based on proximity with menu was annoying, but I can't think of a better solution.
Not changing the current system, more enemy and bullet types would improve the game by a lot.
The turret felt underwhelming.
I like the multiplier-based upgrades. Flat values make it much harder to estimate the value of an upgrade.
So, I came back to this after I got a message about update and bonuses and stuff. I didn't get the promised supply packages and 30000 event tokens, why's that?
@zutharux it's no longer "free to play", it was GREAT f2p bullet hell shooter a year ago, now that Kabam got it, its more of a laggy-pay2havefun kind of game.
