A fun twist on Suika - the smoke/fog visual effect was neat, and I really enjoyed getting a ball in the intended position after bouncing off a few slime pegs!
Only minor issue for me: I had a bit of trouble at first with some icons looking similar and getting them mixed up. I eventually got the hang of it but definitely misplayed a couple of times initially.

Yeah, I think that's something where I'm so used to it that I don't even notice anymore. I'll add some greater visual distinguishability between the standard attack and defense icons in a near-future update.
Further out, I'm planning to add an item that gives you a "Bash" peg - it'll act like the Slime peg, but damage the targeted enemy each time something bounces off of it :)
