I'm stuck in the Hollows on the platform trying to throw the bomb growth at the red crystal. But no matter how many times I use aim mode and throw the bomb, it always flies horizontal and attaches to the bottom of the platform; I can't seem to get any elevation or arc.

To be clear: I press E to grab the bomb, then Q to enter aim mode (and move the mouse to get the reticle over the red crystal), then mouse middle button to throw.

Am I missing something?
