Hello there! Could you please give me more details about what specific part is too hard for you, and what specific mechanic you're having trouble understanding and/or using?
I'm sorry, but I will not "remove" the Ventilation part as I have worked months on it. And "fixing" goes more on par with balance, not fixing, as it's not a bug per se.
I sure do! Here's the Changed3D Discord group! https://discord.gg/njGacraY
