As 3D game development is completely foreign to me, I cant even comprehend how you made this in 72h. Amazing stuff!
A full automation game entry and I did not encounter a single bug, incredible.
Visuals were great. While I found some of the audio was a little too loud at times, such as the "invalid action" sound, it overall felt good.
Obviously this game could benefit for many quality of life improvements such as being able to override existing conveyors or deleting something with a key instead of having to switch to delete mode but I'm sure you are very aware of this and I would not expect you to have all that in the short time you had to make this.
Would have loved to see the robo cat be a bit more involved and react to the snacks we're feeding them as, besides the fact they were there, I didnt real feel like I was building a factory for them.
The tutorial at the start was such a pleasant surprise, it worked flawlessly and was to the point. Loved it.
HUGE congrats for submitting this. Not only is it really impressive but it has also inspired me to get into 3D. <3
