I made this for the js13kgames challenge.
I submit it in a rush so it's far to be quite finished. Apologies.
The theme was the four elements : fire, earth, water, air.
So let's say you are a famous alchimist, poorly drawn spartans runs toward your home and they looks angry.
Use your powers to defend your laboratory, build defences.
Each element give a unique capacity for the tower, it's possible to combine elements to upgrade the tower.
Just kinding ! I didn't have the time to implement this, so it's pretty basic actually.
The game is played in a isometric 3D view.
The map can be rotated when dragging it, which allows to see hidden spot and produce a nice effect.
Drag and drop an element from the right menu into the map to build a tower.
