Use the Element Gun to control the elements, and solve the levels.
To change the element touch an element plate:
To defeat an element, change the Element Gun to its weakness.
The gameplay is not very exciting and it seems like you may have run out of time while making it, as there's no sound, little art, and only a few levels.
The main problem with the game though is that it ends before it really does anything very interesting with the elements. I also had a hard time remembering which color canceled out which color.
It would remove a lot of the puzzle in its current state, but I think it would have been more fun if you had designed the game with the ability to toggle between elements with a button(s) instead of the slow-pace of walking to the element pads repeatedly. And maybe only start with one element, and unlock more as you progress, so you have time to remember which color goes against which other color.Submitted
