Very fun game, and a very unique genre mix! I really hope you expand this one and consider turning it into a full Steam game. The 3D mode is a super cool idea and I think there are a lot more mechanics you can discover here, and fun ways to continue interconnecting the modes.
I really like the situations where your weapons get damaged and you have a choice between continuing to fight at half capacity, or taking a break to repair. I think there's a lot of cool ground here to continue expanding on concepts like that, adding more ship systems to manage, and creating a variety of interesting tactical choices. Great work on this one, and I'm excited to see what your team does next!
