Getting all the weapons to sync up was definitely something I wanted to get working, and I'm glad that it was satisfying and worked well! The SMG is definitely the weaker link of the three, and there's currently plans to turn it into more of a burst-fire weapon post-jam, with each beat hit firing 3 or 4 shots instead of a hold-to-shoot as it is right now.
That map void issue is actually one of a few bugs that happened last-minute due to having to switch from a web build to windows - the other annoyingly being the restart button takes you to the main menu instead of loading the current level again. Which - naturally - is a really annoying combination.
Thank you for playing! I'm glad you had fun!
