Thanks for the feedback. The void level wasn't implemented so the portal wont do anything. hopefully gonna work on it a bit more. The idea with the intro was to only show it the player on new game but because i didn't get round to the save system it was a new game every time.
Also yeah I used vertex colours. The ps1 didn't have shadows so in game like Spyro and crash bandicoot they used vertex colours to darken areas and bake lighting. Most enemy's were done purely in vertex colours, no textures. Also found they did the same for lighting which is how i did Dennis's shadow. Just used an inverted light. You can really see this in games like silent hill that used a torch.
