Practice Level

The practice level will spawn a minidrone after they are unlocked in the main game.

If you spend enough time in the room you will receive research points. The sign will let you know when this has happened. This is meant to encourage people to practice using their new upgrades without feeling like they are losing out by not getting more research points doing something else.

 

The ceiling is fake. There is a warning sign at the very top of the level. If you can get to it then it will spawn an enormous number of death balls. Defeating them will cause the warning sign to change to an "upgrade sign" and touching that will unlock the Jet Pack.
