Thanks for playing! Glad you like it
I thought of the theme as limiting the player in space, where to place these towers. However i already got some feedback telling me this wasnt very clear in the game..
The lava effect i did using the Universal Render Pipeline (URP). In Shader Graph i used the cells parameter of the Voronoi-Node.
Look it up if i explained it too poorly (or contact me on discord :P). It's really not difficult :D
Also: I will (hopefully tomorrow) upload another version of this game with more levels! :D
