Hey @haw602043 welcome to the forums!
Thank you for your post and sorry that you are experiencing issues. However, we may not be able to help you with this issue if you do not complete the template fields fully.
Without a code excerpt and/or the link to your Repl there won’t be much we can do to help you. A screenshot of the expected output would also be appreciated.
The more information you provide at the start, the easier it will be to identify the problem.
(If you’re talking about the game Slope and you want to remake it:)
Slope is a very complex game that was made in a separate engine. You can’t really make it on Replit, but you can embed it in Replit. Try forking this Repl: https://replit.com/@jscraft/Slope
they probably mean implementing slopes in the environment of a platformer game
