Thanks for your kind words and feedback! Unfortunately we weren't aware of the problems that Control+WASD may cause in browsers :( We have added a note in the description that we recommend to use the key arrows instead and we will definitely keep it in mind for the future. Additionally we made a little guide on how to gain crystals and general game progression. Thank you very much that you took your time to point those problems out, that was super helpful for us! And I am very happy that you still liked our game :)
