Thank you! Interestingly, the graphical style mostly grew organically from a random technical decision I made to represent every sprite as a single 64 bit integer. I guess that vaguely emulates the hardware constraints games were dealing with back in the day, which is why it's visually so reminiscent of old games.
Thanks also for the suggestion. I had some more ideas for this game that I didn't manage to get working in time for the jam deadline, as well as one or two that I came up with afterwards, so I might still revisit it later!
