Couldn't quite figure it out, but it does look interesting. Curious what inspired the name Isekai Wormhole?

It's a bit like Stargate and a bit like Sliders, both go to isekai in a way. It's weird how everyone has the same reaction that they can't figure it out. I'm starting to wonder. What was difficult to figure out? Mouse control? Speed? I never actually used the Up/Down /Left Right controls I added, just always hands on numbers and controlled using mouse to keep in center.
Did you select a speed and start with W? There might be some issue in some browsers... I only tested it in Brave and on Desktop.
Isekai is just "other world", not just reincarnating but also going to different world is valid (Like in "Isekai no Seikishi Monogatari" or Escaflowne) - reincarnation just got more hyped lately (Yes Truck-kun hits people since 1963/1982...)
