Don’t take that feedback too hard please - this was a game jam with a limited timeframe and it’s understandable if assets get leaned on in order to ship a working game. The same guy was complaining in the community posts for something else just a couple days ago - he’s probably just looking for things to get mad about.
I played your submission and I thought it was pretty nicely structured, gorgeous visually, and the portal system was a really cool touch (I did something similar in mine so I’m partial to it haha). Please keep doing what you’re doing! And I look forward to a full release of The Atrium if you decide to keep working on it!
