Why does it cost more here than on Steam?
It includes Android + Mac versions. If you have bought the itch.io version, you will receive a Steam key too - via email.
Now that you offer a Steam key with every purchase, a "Get Steam key" button appeared on my purchase page (and for any previous buyer I suppose). But I also received another key via email, as you said... So... which one should I redeem now? XD
Thank you for the upgrade, by the way!
