I love the aesthetic! And the atmosphere, very fun. I found the stairs a bit tedious and they whittled my timer down a lot, but I liked their inclusion, just...not so tall.
I also struggled to understand what the 3rd and 4th symbols were. I could figure out Gamma & Omega easily, but the other 2 escaped me. That could just be me though, my physics is a bit worn.
Overall very cool, and very fun! Well done :)
