I see! I can totally see the vision now. I'm gonna be honest, it didn't feel like a roguelike to me! I assumed it as a hotline miami alike linear game. The upgrades feel linear too and they were abundant enough to have them all even before the last level.
Anyways, to cheer this up again, I want to add something I didn't add in my first comment, this game has really serious potential to be expanded into a full game. If you can take the opportunity I think it's really worth it. It gave me full devolver digital game vibe. Not sure what is the process for them to publish someone but i can totally see it.
