Hey, thanks for the feedback. at some point I'll be making and uploading a post-game jam version, so this advice helps a lot, and that crosshair idea sounds cool, I'll keep it mind.
I'm sure that Budgeri, the composer, will be uploading the full soundtrack for this game on their YouTube channel at some point. here's the link to their channel sometime soon:
