Idle Geometry Defense tasks you with holding off waves of red cubes across infinite levels by upgrading towers and deploying supplementary units. While it promises full 360° battlefield rotation and time acceleration, the experience is hampered by manual progression between levels and limited upgrade depth, making it difficult to actually idle as intended.

What players are saying

▼ Not recommended 0 hrs
The way it is right now I cant recomend cause:
- No way of playing in window mode
- Everytime you beat a lvl you have to manually go to the next so you cant idle
- Everytime you beat a lvl or die, you have to manually change to speed 3X again
- There are only 5 or 6 things you can improve and it doenst seem to have a reset
- There is no volume control

If the devs change that I will change this review and buy the game again.
