Thank you! I really appreciate that, and your earlier comment too : D
There *are* areas on OCS/ECS/68000 that have slowdowns yeah. The judders are probably down to YT compression and emulator settings though. Real HW has slowdowns but no jerky screen updates.
I'm taking some inspiration from the SMS version, especially for the 3rd level which will have a slight ancient Greece theme for the field section to go with the harpies and medusas and all that.
