Hi! Thank you very much for your detailed impressions!
I tried to make the controls as easy as possible, so right click is always examing and left click is the action of the displayed icon (unless you are combining something where right click is cancel for convenience). Maybe I need to have a separate text to make this clear.
As for the drawer: Maybe add another text hint pointing to the drawer appearing after a while? In most cases it is something that is totally obvious for me (or any dev) where players are stuggling in the end. I was hoping that the player would just check out the interactions (as the cursor indicates when pointing at something interactive further away as well).
Thanks again, I will think about this.
And thank you for the all the positive feedback as well. I have seen some questionable usages of "voxel", too. I'm also breaking out of the "restriction cage" of voxels here and there to do a smoother effect or something, but I think I have found a "final" voxel look for the game that I like. :)
