Hi Surli! This a link to my Google Drive for you to get a copy of the project:
https://drive.google.com/file/d/1q6i6HEYHISNom3uxDiM020lgyb3fX1x3/view?usp=drive...
The ZIP has a folder already named Asteroids along with the project file inside. Extract it somewhere and import the project in GameMaker Studio 2.
Or, if you have the Trial, first make a backup of your own Asteroids project folder, renamed say Asteroids_backup, and then extract the ZIP in order to overwrite the Asteroids folder existing content.
The Asteroids.yyp will be with the same name, but inside with different references to resources. Open the project in GMS2. It should work.
There is a Warning.txt note in Resources/Notes. Read it before doing anything else.
