Thank you for your feedback. I agree totally with you. It's always difficult as developer (after being used to the game) to find out what's "strange". I've written that I made 99% by myself, but I can't accept that compliment because the ripple effect was the only thing I searched in the internet( I'm not that good In shader coding).

After the Jam I will update the controls of the player. Thanks! :)
