There should be longrass-bread (cornbread) in Ark. Put longrass and oil in a preserving bin and wait, then you have dried longrass. Then grind it up in a mortar and pestle and you have longrass flour. Then mix with water in a campfire and you have cornbread! Should keep a long while and fill a lot of hunger. This would be awesome. Up so Developers can see!

Once you activate jet mode you will automatically be moving forward, but if you also press your forward key it will go faster, and on top of this it has a boost mode. (assuming sprinting with jetpack)
It also has an evade while in jet mode which makes the dono do a full 180° turn.
