Thank you!
It's really great to hear that you recognize similarities to STS, but also see how the party aspect adds novel layers to deckbuilding and strategy. That's a big goal for the project, to keep the best aspects of STS that make it a classic, while creating meaningfully distinct gameplay. I've tried to make design decisions that add genuine depth, but not burdensome complexity, and I was hoping that the end result does feel unique.
Thanks also for the feedback on the UI and audio, I totally agree regarding tooltip hitboxes - that needs cleaning up. With respect to the audio/soundtrack, it's very much a first draft, the loops will definitely be extended, and there's a lot of orchestration left to do. It needs some time and attention now for sure - I appreciate your honest feedback!
