Something i see very often. Im not sure if lot of creators are aware of it, but some keyboard regional layouts have z and y switched. And its really pain to play with its layout (as you can imagine, in that case its not z/x but y/x). Somebody can say: hey, but it should not be problem for you to change keyboard region... i say: yes you can, but its quite annoying. There are plenty nice keys which are next to each other (space/alt, shift/ctrl). I made this post to inform creators, maybe someone will read it and will think about it when creating game. Thank you for reading it :) Have fun with LD
