Whoa! This is really cool, it reminds me a lot of the golden age of PopCap ( ❛ ᴗ ❛).
There are a lot of nice design choices in here from subtle mechanics to level layout, but if I had to zero in on one, that would be the skeuomorphic design of the firecracker snake/dragon and the sparking tail fuse—it really does explain half the mechanics at just a glance ദ്ദി◝ ⩊ ◜).ᐟ.
Definitely the most creative use of the theme I've seen so far! Snake but the snake is made of dynamite ৻( •̀ ᗜ •́ ৻).
