### 3/5 — Nice game but too many ads

*2022-06-26, version 1.9.2*

Mostly just wish you could get rid of the pop up ads

### 3/5 — Could be better

*2022-01-15, version 1.9.1*

I like the concept. Pop up ads are way too numerous. Drop rates are iffy. I’ll keep playing for a while, but the ads and drop rates feel tedious.

### 1/5 — Too many ads - avoid this game

*2022-01-03, version 1.9.1*

Way too many ads to be enjoyable. The ads are insistent and even with a purchase you still are forced to watch tons and tons of ads.

### 2/5 — Unplayable

*2021-11-08, version 1.9.0*

Too many ads.

### 4/5 — A few bugs but has my heart

*2021-10-04, version 1.8.9*

Could use a few minor updates. Allow to buy and remove ads, upgrade or change layout or base, so that instead of straight down, it’s more open and accurate to real concepts. Cubes and clothing have a problem, and drop rates need to be beefed up a little so more happens (five runs on one map for two item drops was not fun to wait for).

### 5/5 — Great game

*2021-09-20, version 1.8.9*

Love it

### 5/5 — Too many ads

*2021-09-10, version 1.8.9*

It’s a really great game but too many ads

### 3/5 — Ads Ads and more Ads

*2021-09-03, version 1.8.9*

Fresh ideas but basically the same shelter defense game. You can play your own expeditions which is cool. Some rpg elements here and there. Really liked it at first and knew there had to be a catch and than the ads showed up. 

Open a chest? Ad
Want an item for expedition? Ad
Need healed on expedition? Ad
Finish an expedition? Ad
 
So many ads and it’s the usual timed ads but than they force you to tab out to the google store. Certain ads dont give you the x to close the ad forever either. So you have to close game and reopen. They also make the x hitbox extremely small which makes it tab between the ad and the store repeatedly. At some point you realize you’re spending more time in ads than the game. 

Not really my idea of gaming but to each their own. I have the feeling most people won’t spend much time in this game. Shame because it has a good foundation.

### 5/5 — Great game

*2021-05-03, version 1.8.8*

Fun

### 5/5 — Very good

*2021-02-10, version 1.8.8*

Love this so far! Good job! 👍👏
