Iw opuld like to see lot of little 3DGS games as good and complete as this one

The graphics features are some standard and good ones !
The navMesh system is just great, no more worry about complicated path finding.
Shiva provides lot of simple to use already existing features to make your game.
And i find the scene pretty well done , with a good bunch of assets around the house, and with lot of animated with their AI, this is a complete game running pretty well

They could have put some large bigger terrain with zombies only, but i prefer a small level with lot of details and things and lot of zombies.

You can make a world if you use scetions of levels , like Zelda games indeed
Or you could make some Devil May Cry , Resident Evil game with good detailled scene without worrying.

Indeed it's indie engine and not to remake Skyrim with it, but i find it really great for that price ( All mobile , webplayer and PC publishing and more ...)

I just posted on the tools to says for more 3D artists than programmers: "Wow for that price, and all that mobile platforms !!"
