Thank you for playing! That is most certainly a bug. Currently, there seems to be an issue with the web player on some device/browser pairings. If possible, could you try using a native build? They are stabler and is generally more performant than the HTML5 version. I'll look into fixing it as soon as I get back on my computer.
(Edit: This issue should be fixed in the 1.0.1 WebGL build.)
