About this game

WALKING IN A WASTELAND WONDERLAND 🚧

That’s how the song goes, right? Well, now it does, seeing as how the apocalypse has come and gone and the last remaining survivors, yourself included, are left to rebuild society, starting with the local jail! Unexpected, yes, but just because the world got laid to waste doesn’t mean that all crime stopped. Craft, build, and defend your prison hub as you rehabilitate inmates while also building a shelter and trying to survive in this idle prison RPG.

THEY’RE IN THE JAILHOUSE NOW 🏚️

This game combines all the fun of idle games, where you’ll craft buildings, workbenches, and more that will collect resources for you in the background, with the fun of RPGs as you work to clean up the area, manage and expand the prison, and become an all-around jail tycoon. Along the way you’ll also have a chance to help rebuild your world, one reformed criminal and beautified spot at a time. Don’t go soft yet through: you’ve still got to defend your territory and survive!

We think you’ll love:

🛠️ Crafting: Simple items can turn into deadly tools and crazy weapons in your hands, all it takes is a bit of skill and a touch of forward thinking. Collect all manner of items as you clean up the last dregs of chaos, and then use these to help build new prison wings, weapons, and gear. Your survival depends on it!

⚙️ Upgrading: Once you have your base items, don’t sit back on your laurels! Upgrade them to the max so no matter what the wasteland throws at your shelter you’ll be prepared. In addition to weapons and gear you’ll also need to ensure your survival by constructing buildings and then setting up defenses and protecting them. Who knows what’s out there!

🏔️ Exploring: As your need for resources grows, you’ll have to travel further and further afield to collect items to keep your prison running and ensure your survival. Enjoy the opportunity to see a whole new world post-apocalypse and explore all manner of mysterious places as you roam. Don’t be afraid of a little danger though, that’s usually where you’ll find the best loot stashed.

👨‍🏭 Growing: Grow your jail, your world, and even your character! The more you progress, the more skills will be unlocked, thus boosting your little guy and helping you survive.

🎮 Playing: Your survival might be on the line, but this is still a game! You can enjoy this idle wasteland exploration game anytime, anywhere, as no internet connection is required. Squeeze in a little world building and jail building no matter what the situation.

SURVIVAL OF THE SMARTEST 🧠

I just went to launch my game and my progress was completely restarted. No option to restore exists. I have also attempted to reach out several times with zero luck. The games description is not even accurate. There are no monsters, it's literally just watching ads to build a prison. It is fun, but definitely not what it is listed as. Clearly there are some serious communication and advertising errors.

⚠️🚨This is a good game I enjoy playing. But....There have been a couple sketchy ads. One ad has a graphic that blinked you're a winner and had a false Amazon page to click on. I don't remember the other one but I do know it was a scam page. So I would download it with CAUTION ! and beware of the ads don't believe them. I would have given 4 stars if this game did not have some scammy ads. Oh and the vines we have to endless chop for nothing sucks.You get nothing for them.Then they regrow! 🤬

These games are fun at first but they usually evolve into collecting items, running out of items, and watching ads for items to build the same rooms over & over again & this game is no exception. I was half way through level 6 and Hammer 9 by the time I got bored with the same rinse & repeat system. 3/5.
