Thank you for your kind words! And yes, this game was heavily inspired by top-down shooter classics like Gungeon, Nuclear Throne, Soulknight,...
Yep, the dungeon is randomly generated. I found this video on YouTube that explains a simple proc-gen algorithm and Huy implemented it. Later I also tried this to make the rooms feel more random, but ultimately we decided to scratch it because we didn't have time to generate a decent map.
And yea, we also feel like the game would need a lot more balancing. I guess play-test by 2 people wasn't enough, since we are the devs and we know exactly how the boss works so XD But again, that you so much for trying our little game!
