Glitches and Level 2 Bug

[ToeRubs]

• Companion Cube doesn't spawn on an old 3DS (My DS is an Old 3DS, so I know it doesn't work from my experience, but according to another issue, people said that it didn't work for the New 3DS or 2DS either.).
• When you put two portals on top of each other, they allow you to pass through walls (Patch the Companion Cube first, because this allows you to beat the level without one.).
• On level two, when I use the portal it glitches out, and when I reload the level, the top screen goes black (When I try to exit to homebrew (after it glitches), my DS freezes and I have to FSD)

Sidenote: The 3d doesn't work while it's loading the level on the title screen, but it's a minor issue, and I don't know if that can even be fixed.

Otherwise, I love the game, and I can tell that you put a lot of time into it. I love what you do for this community! :D
