Greg Micek writes : "Caffeine is an interesting take on a psychological horror game utilizing exploration from a child’s perspective. Different emotions are stirred up; if not even a completely different mindset once players acknowledge this. The player is vulnerable and very exposed without much protection or light sources to guide them along. It’s all relying on the exploration to figure out what’s going on. A combination of suspense and uncertainty, lore, and puzzle solving will potentially capture the attention of players and keep them captivated for the entirety of gameplay."
