At this moment there is a development stall in the project due to onmouseover/onmousedown deprecated in latest CGE versions. So... I still haven't remade the interface CGE-way (which wolud also allow me to port the game to Android).
I've made an GitHub repositorium for the game here: https://github.com/eugeneloza/Project-Helena

Meanwhile I've recorded an annotated epic battle at 166th difficulty.
