Thanks for helping to playtest it!
One feature we're hoping to get in post-launch is the ability to eat candy to locate cartridges. This was a feature in the original E.T. and was something I couldn't adapt in time. That and an indicator for whether or not a cartridle is available on the screen should help immensely.
I'm also weirdly happy that the warps between areas are disorienting. The cube world of the Atari E.T. was adapted into the world design for F.U., and can be seen on the top/bottom areas (where all exits lead to a top or bottom entrance) and the side areas that link together in a loop when walking sideways.
I will also look into auto-fire post-launch. Thanks again for playing!
