There's a flash version of portal. If the dimensions work out, maybe you could just rip some of those sprites and use them.

There are a few flash versions of portal. Of the two I've played, both would be somewhat difficult to implement, and one of them I don't really like the sprites for. Right now I'm most likely to use CHK4's sprites for the CSE version, or I may make my own.

that's looking sweet!

Thanks! Too bad you don't have an nspire

EDIT: I found some serious issues with my portal physics as they are now, so I'm going to completely redo them. This might take a few days.

EDIT 2:
Here's the new portal/physics engine:

Next I'm going to make some changes to portal shooting, and then I'll move on to other game play elements.

Nice work on the engine!

Thanks!

Today I reworked the method of shooting portals, changed the gravity, jump height and velocity limits, and also fixed about 5 or 6 bugs. Now that I'm finally happy with the basic layout, I'm going to implement sprites and then start working on other game play elements. In a week or so, I'm going to take a quick break from this to work on a Sonic based game with Ivoah. It shouldn't take too long, especially since there's two of us working on it. Once that's done I'll be working on this again, (and I don't think you'll be too disappointed with the other project either if it comes out how I plan).

I love the new sprites, are you gonna add a ceiling?

I see you borrowed the sprite form the 83+ version

Not sure exactly how his walking/jumping animations are set up, but I think it's basically the same

I love the new sprites, are you gonna add a ceiling?

Yup, this isn't an actual level, I was just messing around

EDIT: Added cubes, energy balls and toggle switches! This is finally progressing!

this looks truly amazing, i literally cannot wait for the final version

I'm glad you're excited

I made portal shooting instant, here's a video to demonstrate portal shooting, energy balls and toggle switches:



(the screen recorder i used maxed out at 30 seconds so you miss the end of the level where the energy ball hits the switch, opening the door on the far right)

EDIT:

Changed around the level, added droppers that can spawn energy balls or cubes, added ability to put the aperture labs logo on blocks:


Changed CKH4's banner thingy to match the current design:

Looks amazing, great work   The only thing I would suggest is to look into the actual potential of energy balls in terms of using them for puzzles.  There is a reason they were removed in Portal 2, I feel that they were one of the least entertaining elements and give rise to puzzles that end up being a lot more twitch based and frustrating.

Thanks, it means a lot from the maker of the first portal on a calculator ^.^
I think I'll keep energy balls for now, but I'll keep this is in mind when designing puzzles

Also, I added energy beams and glass! Here's a new video:

EDIT: New Sprites!


EDIT 2:
I made a lot of progress, the most noteable update: turrets!

(screen recorder is a bit laggy)

I will release a beta version fairly soon!

EDIT 3:
I added heating chambers, where the background slowly fades to red, until eventually, you die. (Almost like a time limit)

Nah Mate!!!!
I seriously thought for a sec that you somehow added colour to the 8x calculators and played portal on it

Well the 84+CSE has colors, and the 84+CE and the 83PCE will have colors too...
Plus, there is a color version of Portal on the 84+CSE in the works by MateoConLechuga.

Thanks for the compliments and support!

I added a pause menu:
