Description (written by the developer; not a statement by this register)
this is a reupload of an old open-source portal game made by another creator. i re-uploaded that creators game with a new name with the intention of developing it further. nothing in this game is developed by me. the original game was taken down (probably?) and this is now the only form of it that exists. i originally planned to use the open-source portal mechanics to develop a full fan game with a couple of friends, but those plans were far too ambitious for a couple of middle-schoolers. if anyone is able to find the original game or knows who the original developer is, please contact me and i will either take this version of the game down or provide credit and keep it for archival purposes. i do not want credit for something i did not make!!! thanks for playing :) Controls: [WARNING: this game is NON-FUNCTIONAL. it will NOT recieve updates!] E: Interacts with the environment. Picks up cubes, presses buttons. Left Click: Shoots Blue Portal. Right Click: Shoots Orange Portal.
