That is the message you get if the file is named Info.txt.plist, so make sure that "hide extension" is off when renaming so you can make sure it's "Info.plist".
Yeah, I don't know about playing on a keyboard. With my 8BitDo Pro 2 it was as I said, playable but not ideal. I'd definitely pay for a "proper" 3D sequel that was more extensive, and they'd have time to refine the controls.
Honestly the controls need work. The game's playable as-is, but there's a certain amount of control-fighting and fiddly-ness that ideally shouldn't happen. For a free game made in a short time it's impressive so I give that a pass.
Still, there is something here that sucks, but it's not the game.
Are you sure about that? It's not a very demanding game to run. Anyway, just download it for yourself and see; your computer will not explode. (Almost certainly. ;) )
It's a custom engine. As it says on the github source, "We haven't done a lot of 3D development so much of this is not very optimized, it's coded in libraries mostly intended for 2D games, and we put it all together very, very quickly." If you want the details go there and look at the source.
Any text editor will do, but with TextEdit, uncheck 'If no extension is provided, use ".txt"' Though if you save it as .txt and rename it to .plist it's the same (but make sure it's actually .txt rather than being appended as .plist.txt, so it helps to have "hide extension" off).
It does work on MacOS; check the "more experimental platforms are available" link near the top of the page. Seems to run perfectly here, however it's currently very bare-bones and you have to run it from the shell. (Unzip the file, cd to the unzipped folder and type ./Celeste64) If you want to turn it into a proper app, follow these steps:
Make a folder called Celeste 64
Make a folder inside the Celeste 64 folder called Contents
Make two folders inside the Contents folder, one called MacOS and another called Resources
Unzip the Celeste64 Mac zip file
From the unzipped Celeste64-v1.1.1-macOS folder, move Celeste64 and the three .dylib files into the MacOS folder you made (Celeste64.pdb doesn't seem to be used?)
From the unzipped Celeste64-v1.1.1-macOS folder, move the Content folder into the Contents folder you made (also works if you put the Content folder in the Celeste 64 folder)
Go here: https://pastebin.com/JzF6jvsH, copy the text, paste it into TextEdit or some other text editor, save it into the Contents folder you made as "Info.plist"
Rename the Celeste 64 folder you made to Celeste 64.app
Launch and play!
If you have problems with things not working, make sure you don't hide extensions so you can confirm that the file names are correct (e.g. Info.plist isn't Info.plist.txt). Also the icon might not show up immediately; if so copy (not move) the app elsewhere and then move it back. If you need to get into the app folder after it's turned into an app, right-click and do "Show Package Contents".
