i believe the items are spawning ouside the playable area, also the graphis show you have to press a instead of space or left mouse, i know you chracterize it as action button but that may be the reason of the complaining
Yes that was a bug we couldn't quite fix in time, but other items should still be spawned in the play area. The "A" for action turned out to be a big goof, definitely on the short list of things to fix!
