Crystal Keeper combines tower defense with active resource management, asking you to mine crystals while fending off enemy waves through strategic upgrades. The survival-focused gameplay demands real-time attention rather than passive progression, making it best suited for players who enjoy hands-on tower defense over traditional idle mechanics.

The basics are really good, but it's def not idle! Was hoping for permanent upgrades between games in order to improve.
No disclosure of using AI. Files labeled ChatGPT and Photoroom. I was having fun despite the many bugs, jamming to the music. Man I knew it was too good to be true.
Small little TD Game. Its not really Idle and still pretty buggy, for example I died while being afk and the game didn't stop, so there was no way to kill me again so when I came back i had the 40 Waves completed. BUT apart from that I can definetly see how I would get a few Hours of Fun out of this.
