Helper mod for Celeste that adds a 2D equivalent to the world portals seen in other games (e.g. in Antichamber).
Non-Euclidean Celeste go brrrrr
Assuming you are familiar with building Celeste code mods (as explained here), this mod can by built by cloning this repo into the Celeste/Mods/PortalRenderHelper directory (i.e. there should be a file at Celeste/Mods/PortalRenderHelper/everest.yaml), and then by running these commands in the PortalRenderHelper directory:
dotnet restore
dotnet buildIn addition, there is a test map packed as a separate mod in the TestMap folder. To use, add a shortcut at Celeste/Mods/PortalRenderHelperTestMap that points at the TestMap folder in this directory. (Alternatively, you can move the TestMap folder to the Mods folder.)
