This is my first project! I've started using the Portal Returns level editor to begin working on This Is the Only Level CE while @JWinslow23
works on This is the Only Level 84+.
With a lot of help from @MateoConLechuga
and pretty much everyone else, I can make this happen, and learn on the way. Maybe if I ever finish, I could use Portal CE's engine to port Axio Man...
Here's my progress so far: I have nearly proportionally recreated stage one from the original game. Because there is no scrolling in Portal Returns, the stage is separated into two levels. I had to substitute many things. Where vertical wall spikes and upside-down spike tiles should be are the red death fields, and where the entry/exit tube is there is just either empty space or a blue field. I put in a blue field where the green door would be, and three red buttons where there should be one large red button.
I have changed the jump height to about the same height as the game, which is about 20px high in Portal CE.
Tell me what you think, how I should start to go about this, and if this is worth taking on.
I also made sure you can't portal cheat.
