You can see videos from this game that I made with Tricenz-64: https://jpmartin.itch.io/defense-factory
I am planning on adding tutorials and videos about Tricenz-64 itself later, but not yet because it's still early and the features and interface are still in flux.
The program itself comes with documentation and helpful little demos, so if you're considering making your own games you should definitely download this and check out the code for the demos to see how games are built with Tricenz-64.
