Love that you enjoyed the theme and art, fellow math geek :3
The issues you mentioned aren't unknown to us. Sadly we just had to rush in the last few hours of the jam to get some emergency fixes through, and so these smaller QoL bonusses like hit feedback and not-terminal bugs like not being able to go back into the game after dying just didn't fit within the timeframe
Thank you for your feedback tho! It's nice to hear that people vibe with the concept behind the game
From what I know, none of us have any concrete plans to work more on the game in the near future, simply because we might now have the time for that. For me it's because there's already like 2 games I wanna work on and that backlog just keeps increasing with more game jams <.>
