Hey! Glad you liked it! If you press E on the white canvas, you can paint on them too. I should have wrote down the controls, and it was definitely on me that. Glad to hear it was fun, my main concept of decay was from the view of an artist, and while drawing was fun and all. I thought it was rather boring to leave at that with no objects to interact.
As such every object in the level is completely interactable :D
If I had more time I would have added more levels, less lore dump, more in the room itself, goals and perhaps driving, since it was planned to have like sections to tell the story as you deliver stuff around too. But sadly had to compact it, plus when I went through it again I thought it was best to limit it XD
