A very solid base of a game, I liked all the elemental combinations although the effects of them were more or less the same (DoT) the idea is great. I wish it was easier to select the elements I wanted, trying to switch from water to electricity after I got a bunch of different elements took too long and the water effect would wear off before I could shock them.
Really needed sound effects to elevate it and an ability to restart when you die instead of just having to refresh the page. I thought the game crashed the first time.
