I say the graphics were my favourite aspect but I also loved the mechanics and sound, also the blurring effect looked really good.
I played this game for about 20 minutes but I got stuck on the level with the large tree and tree in a pot (sorry i forgot what level it was) I wasn't able to jump over a wall because just as I got near the top I would jump away from the wall. I'm not sure if I was doing something wrong or if it was impossible. On several occasions I took me a while to work out where I was going, I don't know if was intentional or not so if you want that to be part of the game I would keep it in.
An option for 1080p resolution would be nice but overall I enjoyed the game and really like the art style.
Keep it up and I look forward to see what happens with this game.
