I like the simple and effect gameplay. the music really captures the feel of the game. I don't think it was confusing at all if you treat this game like memory style game, I was able to figure out what everything is after 3 attempts at the game. Overall great entry! 

I love the minimalistic artystyle and especially the audio design (sounds and music), it sounds really really good and I value audio a LOT

It's a pretty good game, but it took me too long to figure out what I had to do in the first place. An ingame explanation would have been nice. Once I figured out what to do, game was pretty fun :)

Hard mode was also challenging, but fun
