First of all: thank you for playing and your honest feedback. If I had to do it again I'd do a lot differently. I wanted to make the vacuum particles brighter, I wanted the frost overlay to be procedurally generated and creep in rather than just changing the alpha, but in the end I didn't have the time and I don't have a sense for graphics 😅
A grace timer is a brilliant idea that I simply didn't have, maybe I'll get back to the project when voting has ended
But for source code: sure! Here ya go: https://github.com/tigerplush/ghost_suckers
