Hey is there a Limbo/INSIDE inspiration? eheh Great job, really! And the idea has a great potentiality, I mean for sure a similar-to-Limbo game but actually more mature and with mind and psyche setting would be a great experience IMHO.. Have you played GRIS? Some ideas in it could bring your idea much enrichment.. (the 7 grief stages bring different gameplay and or level design)
Overall respectful job for a just-a-week solo development bringing a narrative and profound experience. Hats off. PS "seek not the light, but the spark that resides in you" hit me.
