@threeli That you very much for the feedback.
About picking up the lights it is a bug that allows you to pickup pre-placed lights you are only supposed to be allowed to pickup the lights you placed and place them somewhere else. The pre-placed lights that you are able to be picked up actually don't allow you to place them again. It's a known issue.
As for the crafting station shooting out the items, it's not a quirk of unreal or anything like that it was just us. It is that when the crafting station mesh got brought in it had a default collision around the entire thing so the items were getting spawned inside the collision and getting shot out even though it look like they are spawned above the tray. We actually did change the collision and made the items spawn in the tray but decided to revert it to this because we thought it was funny that they just got yeeted out like that. Them getting lost through walls or something after being shot out isn't surprising that it could happen which is probably again due to the collision on the rock assets not being properly adjusted. There are some rocks that you can actually walk inside of on one side but not the other. It is something that just never got cleared up in the frantic push to the end even though it is known.
Both issues were down to time really (though we probably should have kept them actually spawning in the tray. would have avoided the rocks collision issue in this case). There are so many things that were planned but never got done. An example of one such feature is that when a light gets powered there would be a chain of electricity going to what it is receiving it's power from. It would have shown clearly that lights can power other lights in range so you can chain lights together which is a pretty crucial mechanic but yeah.
Really glad to hear that you see the potential in it and we definitely will make improvements to it later on for sure. I would be really excited if people were interested enough for this to become a successful full release and not only a jam game.
