I don't know the game in question, but here are a few general hints:
You don't need to boot from the CD. Usually, the boot process just starts the game executable (check "CD0:s/startup-sequence" for the name of the executable and if any other things are done before running the game). Try to start the game from Workbench (if it has an icon) or from shell.
It's a CDTV title, so it might have problems with your AGA chipset and the fact that your computer does not have a 68000 CPU. You need to get a degrader that disables both the AGA features and the caches of your CPU without rebooting. Try KillAGA (Aminet) for a start ("killaga "), if that doesn't work try TUDE (enables you to disable FastRAM, AGA features, CPU caches etc.).
Unless the game requires OS 1.3 chances are good you'll manage to run it this way.
