I really love all the graphics in it. The audio and the mechanics were also great, and although I found it a bit hard I really liked it!
Also it was a bit unclear that you had to put your cursor over the slime to switch to it, like maybe word it a little differently of something there, I know there was a mouse icon but I didn't see it at first lol, and the cursor itself was a bit big, but overall a really nice game!
