Interesting idea. I think you can develop it and add new visuals! Good job!

Cool game : To make the game funnier, you could maybe add a mode where the player goes forward permanantly, so he has to rotate quickly to pass through the obstacles. You could also add some more sounds and different obstacles but overall that's a nice submission.

PS : Could you rate my game please ?

Good old cp_orange style of map. I think you had solid idea but you need more time to polish it.

I know it's just a prototype of your idea and I will give you some advice. Experiment with your game's physics. Create maybe a part where Player must rotate the tube and jump from the platform to platform to get over a obstacle or a wall. Try to make more obstacles which align with the ground so try to make more circles and ovals. I liked how you managed movement. It's not your standard W and S to move and A and D to rotate but you made fully functional 3D space which works. I am impressed. And when you make the final version add checkpoints and save areas where Player can wait and relax a little bit. Next time try to add some sounds like a death grunt or jump yell or something and work with music integrity, the main menu sounds sci-fi-ish when the game music is a future rock. I think the beginning of the game music suits better in the menu while the main part with some tweaks can be in the main game.

I am curious what will you do next with this project. I will check once in a while what you do.

Good luck! And if you could try my game. I am wonder what would you change!

Good game bro 

i enjoyed it
