It's a fun time waster. I like the concept of just eating the people for fuel and completing small missions lol. I wish it was easier to level up without having to watch a million ads (or paying for power ups), but the one thing I will say is that this game doesn't interrupt gameplay with forceful ads. That (and the fact that I'm a venom looking alien with spikes as I get bigger lol) is why I'm still playing.

The game is fun honestly. But it is the normal grindy gameplay with this one. My biggest issue is the clutter on the screen. Too many "buy this pack" and "subscribe with purchase" so it's hard to actually see what you're doing or who/what is around you. Just put all that clutter in the shop. It doesn't need to be on my screen while I'm trying to play. It doesn't make me want to buy it to get rid of it, it makes me want to stop playing.

Fun game. Starting out ya gotta watch ads to grow fast enough to keep it interesting, unless yah wanna pay. If you play long enough you will earn things that get you the premium currency (emeralds) at a decent pace. I did buy one pack that doubles everything that you pick up. I think it was worth it. It doubles the premium currency you pick up also. It doesn't double things you watch an ad for.
