Nepton is a puzzle/RTS hybrid (the RTS elements being really, really light, mind you) where you play as a divine entity conquering a world covered in water. There's some onboarding in the game, but in case that's lackluster here's the short of it:

• Each level has a bunch of enemies and enemy territory
• Kill all enemies and conquer all their land blocks to beat a level
• Gain territory by first raising a block of land, then building a Hole-in-Ground on it and using your creatures to smack enemies
• The War Statue will grant permanent buffs to your creatures' max health and damage
• You need Power to raise land and build structures. Gain Power by defeating enemy creatures (2 per kill) and capturing enemy land blocks (10 per block)
• Right-click on land blocks to order ALL your creatures to go there - and attack everything they encounter.
• The creatures have a mind of their own and once they see an enemy they'll attack without hesitation. You won't be able to order them around when they're fighting.
• The creatures aren't exactly smart so you may have to guide them around the islands a bit.

UPDATE 2019/10/07: Added standalone build (Windows) and configured WebGL build to be graphically on par with the standalone version.
