When are we going to get an update to fix the numerous bugs, and to add more levels/missions? The boosts don't do what they say they do... The productivity boost depends people up, but halves the money output. The loading boost speeds up the forklift, but it still takes the same time to fill a van. There are many other issues too. Please update!!

Okay idea. However, when it takes a week to save up money to upgrade one thing and you're only on the second area...it's time to delete the game. It's an idle game...you check on it every so often, upgrade things, and enjoy your progress. With this game there is no progress making it unenjoyable.

Not much to do, there's 4 upgrades, and once you build them and make enough money for the space station, the game is boring. The ads on the side aren't worth watching. Nether is the 2 minute x2 buff for 30 second videos that might give you a reward, then you have: $10 to remove ads, $5 income buff, and another x2 buff for $10 and a $15 pass very greedy game.

Having an issue when I watch ads to gain money or emeralds, they don't always register to my totals after finishing the videos. I don't mind watching ads to gain some help, but after multiple times of the money or emeralds not coming through, well it's getting a bit daunting at this point. Probably delete if I don't get reimbursed, and the issue fixed. Otherwise a decent time killer game.

I really like this game but there are so many bugs out makes it hard to enjoy. My examples are that I like quiet games. In almost every game I play I have muted but after each ad it let's some sound slip through. I have to go into settings and turn on and off the sound again. Other than that I don't like how I get a notification I can't fix. Like the clipboard in the corner, is always on even when I don't have any missions completed. It's like that for most things and I find it annoying.

The graphics are cute and the interactions between the soldiers and aliens are adorable. However I've encountered a few bugs. Ads seem to crash quite often, forcing me to close the app and restart it. Also, quite a few times now, my purple gems will go from an amount between 75 and 90, then will drop suddenly to 50 even though I haven't spent them. This is very frustrating as I need them for upgrades.

It is a cute game. A standard idle game and interesting. There is a bug where the 2x button is underneath the upgrade lab button and is not disabled when the lab pop up is visible. So when I am trying to upgrade the lab I repeatedly get a pop-up asking if I want to watch a video to double profit. A minor bug, but given that you have to tap 100s of times on the upgrade button it is enough to make me not want to play.

Awesome little time burner. Issues at the last level with numeric values rolling over to near zero, you can't get enough money to finish the game. I recommend you get the add free option, it makes game play much easier and faster. Be careful with the reset player data, you lose any rubies over a certain amount. I'm on my 4th reset and will continue to play. I wish they would add more levels after the air force base. Please add more alien antics!!
