Swash

Swash is an top-down action-adventure game that puts you in control of a powerful, elemental force : water! 

Harness the fluidity of water to outmaneuver and defeat your enemies, and when the moment is right, freeze it into ice to shift the tide of battle.

Controls:

Hold Left Click: Move water
Right Click while holding water: Turn water into ice
Hold Right Click: Move ice

This is my third "made in a week" game (though it actually took 10 days because the scope was waaay too big and I didn't have as much time). 

It's more of a demo that showcases the concept, which I find very cool and unique, but there are still many features missing.
