Nice game! Reminds me a lot of a game I made for GMTK's Game Jam last year, "Greetings from Pair-O-Dice". I even also happen to have a shotgun and wrecking ball! I only spent a couple days on that, so it's cool to see a similar concept taken further and with more polish.
I came here from your devlogs on YouTube which I just discovered, I really like your idea of testing out prototypes with players and then figuring out which titles to develop and how to move forward based on the response you get. I feel like this is the best strategy also, except I only have a tiny audience so far as a developer and am sort of at a loss about how to build it up form scratch. Meanwhile, I'm just learning Unity and sending up prototypes to this website along the way.
Anyhow, I guess I'm rambling. I've subscribed and am eager to see what you choose to work on next. Great stuff so far, and yeah, I think your strategy is sound. Best of luck.
