It's a fun, visually good game for the first 10 levels. It gets very difficult approaching level 20. Ads are long, sometimes multiple ads in one. It forces you to watch ads to get the specific skills/abilities that you have upgraded to use (random choices after leveling/elites). Been stuck for a while now around level 20, even after purchasing a starter pack and some gems. If it weren't for the high price to remove ads and the very difficult paywall to progress, it'd be close to 5 stars.

thought it was a great game, but then it turned out to be nothing but "buy this pack, buy that pack". "Oh, and btw, you can only play for a short time... UNLESS YOU PAY TO GET A PACK OF ENERGY, SO THAT YOU CAN PLAY MORE!". But, even if you get more energy, you will stagnate unless you buy the pack you need to upgrade since the mats you need habe a drop rate of 0.0001%

Game is highly addictive and fun, I do find that its VERY pricy on the pay to win side if you do decide to buy into the game, but for any free players, you'll start off kicking butt leveling up, unlocking and upgrading, but then like most "pay to win" games, you eventually hit a "im stuck on this level" or "now I can't proceed without basically having to make a purchase"...... overall, just keeping it honest, like the game enough to purchase, but some of the packs NEED TO BE AFFORDABLE! PLEASE!

What’s new

1.The Waterdrop chip effect has been adjusted:
Waterdrop DMG +x%, Knockback +x% → Waterdrop DMG +x%, Stun Duration +x%
2. Fixed an issue where defeating the "Wallmaker" boss too quickly could prevent the "Subspace Barrier" from disappearing as intended.
3.When casting your rightmost Ultimate, the Auto-Ultimate and Boss/Elite Enemy Lock-on buttons will now move upward automatically, so they no longer block gameplay.
