My specs aren't great, but I can run most other games smoothly.
- OS: Linux Mint 17 64-Bit
- CPU: 2.40ghz Intel i3 dual core
- RAM: 4GB
- Graphics: Intel Integrated "HD"
- Browser: Firefox 45
I didn't mean to be a pain or anything, but I think due to the very graphical focus of your game (it looks great btw) and that it's in-browser it's probably best played by more recent and higher-end setups.
