This game is currently in beta, so you’re welcome to try it out, but please expect some bugs. Each round awards you 5 gems: keep one, and the others will turn into rocks. Use these rocks to build a maze that delays monsters by forcing them to walk longer and take more hits. Gold can be earned to upgrade your chances of obtaining better gems, and with higher-quality gems, you can create “special” gems that possess abilities like stun or poison.
The monsters you’ll encounter vary in type: some are fast, others are mobs with less HP but higher numbers, and there are powerful boss monsters. You can combine gems by dragging two identical ones together. Build a lengthy maze, but avoid completely blocking the monsters’ path—before emerging from the cave, they will check if a route to your base remains; if it’s blocked, they will stay put.
Upcoming features include: more monster types such as regenerating, teleporting, and boss monsters; additional special gems; a more polished user interface; an Android version; possibly some fun additions like bloons and monkeys; and more scenarios—some potentially exclusive to future premium versions.
