I won't buy it unless perhaps performance increases. I tried it with the humble indie bundle and on both my computers with okay specs it was extremely laggy and noticeably slow. (i5 i5 m480 and an older e6300 oc'd)

For a 16 bit game I just find it sad that it performs so badly.

Tried in linux and windows on both machines (with 4gb ram each) and both did indeed experience the sticky keys.
