Amazing game, it was really fun to play! I'm glad the portal had audio cues because I got lost a few times and only found my way through the portal sound. For feedback I'd say it was a bit disorienting that the character's head followed my mouse movement rather than my walking direction. It would also be cool to have more connections between our world and the upside down (maybe while you look for power-ups, you can see statues that resemble the enemies, etc.) since the time between healing/power-up and fight is a bit long. Other than that, what a fun game and what an amazing execution in just 7 days!
