That was an interesting experience. I try to look for hidden messages in games like this, and I think that's what I liked about it, it giving my over-analytical brain something to ponder. I saw it as semi-literal, I guess. Maybe it's about someone with a health problem (mental or physical) just trying to survive through the day. It could even be symbolic of emotional things, life feeling "suffocating." I didn't fully understand the part of being in a bubble at first before I realized it was likely metaphorical. Like there's you, there's your problem, you're stuck with it and you're struggling to just survive. I took the lack of other people as a symbolism of feeling alone.
Honestly I liked this, even though the gameplay was a bit frustrating at times I did get to the end and enjoyed the minimalistic, pixelated style. I like art games that allow me to think like this, so even if it probably isn't something that I would see myself replaying often (no offense) it's good fuel for my overly analytical mind. Sorry for the ramble. ^-^''
