Alright, I'll copy the exact code that I put in both .bat files:
Dedicated.bat:
start "" "C://Program Files/Steam/SteamApps/common/Blockland/Blockland.exe" ptlaaxobimwroe -steam -dedicated
start.bat:
start Blockland.exe ptlaaxobimwroe
Dedicated.bat can be anywhere, but start.bat must be in your Blockland folder.
Nvm, I remembered you needed to add a .txt file in your Blockland folder.
Put a text document in your Blockland folder named steam_appid with the following contents:
250340
I apologize for forgetting about this step, and after you do it it should work.
