I hope you learned a lot while making this proof of concept, tech-demo-y thing, only feedback as of now is:

• Let me jump with W as well.
• In the future give the teleport gun’s projectile a different texture, so I know what is a portal, and what is not!

Hope you will come back to this and finish it at some point! Ping me when so!

Should also implement proper level borders, or e.g. wrap the player around the border / follow the player with the camera, so it's not possible to get out of the camera's view. Keep adding content! 

I think you've got an interesting idea but it will definitely need some more work like you said. I'm not sure if I missed anything but it seems like there's not much gameplay besides the platforming and teleporting. There are some cool gun modes but not anything to shoot. The level layout doesn't feel like it's designed around the teleporting mechanic.

The demo might be improved by focusing on the teleportation mechanic and showcasing a small puzzle to be solved with it.

Still, I hope you continue to work on it, I would be interested to see the full version one day.

Idk if I am just bad but I don t understand what I needed to do.. I just on the white platforme but what after that?

the concept is pretty interesting and fun 

Manages not to feel slow despite relying on teleportation. Feels pretty polished! Really liked it!
