Edit; Ads work maybe 15% of the time, which is INCREDIBLY frustrating as ads are 99% of how you can progress at a reasonable rate. I've been stuck at the same area for close to 3 months now because ads stopped working and progression is so slow without the boosts. Honestly love this game. While there 'isn't much to do', this type of phone game has a charm a lot have lost. I hope while the game continues to grow and change, it doesn't lose that simplicity.

The ads in the game are so frustratingly annoying. There are ads for everything, including increasing the level's speed to 3x. This would be fine if the ads weren't so extremely sensitive that you are almost always guaranteed to accidentally click on the ad, instead of closing it out. And if you do accidentally click on the ad and get taken out of the app, it will restart entirely and you do not receive any of the level goodies, which is more irritating when you are halfway through the level.

Not F2P friendly. Decent fun for outrageous prices. Want a better (or new) character? You need to drop more than $30 for each one. There is only one high-ranking slime available for F2P players. Also, the pull rates for upgrades are incredibly low, which makes the very high prices feel like a slap in the face. Very predatory micro transactions here, feels like a game made for the whales who spend thousands every day no problem.

Hello! Making in-game purchases only speeds up your progress, it's not the only way to get ahead in the game. There are plenty of other ways to earn in-game resources. So, if you're an active player, you can still compete with others. Good luck!
