First of all, welcome. ^-^
Second, you may or may not know that this forum broke not too long ago and we're still kind of recovering from that.
Now, the pink orb makes Juni run faster, the brown orb with lines in it makes Juni climb up walls, the blue one with one arrow above it is High-Jump. Guess what it does.
The one with a line and an arrow is Double-Jump. The weird machine thing makes Juni glow red when enemies are near or when detecting tiles are placed. The hologram makes Juni create a clone so foes won't see her (they can still kill her, though.) The umbrella makes Juni float through the air. And the keys open various locks in the Objects and Areas bank. The eye makes Juni able to see ghosts.
Now, controls.
Up Arrow=climb up,
Down Arrow=climb down quickly and activate shifts and double-tap to activate/deactivate hologram
Left Arrow=move left
Right Arrow=move right
S=jump and double jump when you have double jump, A=hold to walk when you have run,
D=open/close the umbrella
Q=see inventory
...I think I got 'em all.
