I really liked it, I think it was pretty easy once you upgrade your bombs enough though. I think it was a bit tricky to figure out how it works, the way the bombs explode differently wasn't immediately intuitive. I think one super simple extra mechanic you should've added was make an element that you CAN'T explode, or it will damage you, so you think about exploding things but also avoiding exploding something else. This can also balance out the bomb upgrade since you have more of a chance of exploding the wrong thing. Fun simple game.
