Where's My Water? 2 Dynamics of water and land

Hello everyone I am wanting to make a game that uses the dynamics of water in the game “Where’s My Water? 2”, and the dynamics of the land, I wonder if you could give me a hint where to search and what to search for? how this could be done hugs to all.

I would look into physics handling for the water part. You might want to check around the forums for realistic water or something along that line.

did you get anywhere with this? i was able to produce a tunnel using decals but i don’t think they are mobile friendly. please let me know if there are any solutions to a 2d tunnel or driving water down it.
