A primitive tool for creating Groove Coaster arcade stages.
This is still very much a work in progress. While this program is mostly feature complete, a lot of things may feel unintuitive. This is by design as I intended GCCompanion to just be a proof-of-concept to show that custom stage creation is very much possible. I'll try my best to patch out any unforeseen issues as they appear while also taking user feedback into account when designing the next iterations of this tool.
Take a look at the wiki for an overview on how to use this tool.
You can find the latest release here, as well as "Synchronicity," my example chart that was created with this tool.
