The visual experience here was so great, it felt alien, hostile and grotesque--just like I imagine travelling through the blood would do... haha.
As some people mentioned below the camera certainly does have a bit of jank which makes it quite difficult to navigate at times, and the clipping through walls did definitely take me out of it a bit.
I also felt that after the very first room there were no longer any white blood cells chasing me, so the threat pretty much disappeared entirely. But that may have just been my playthrough.
I also thought that perhaps you could have made the valves be little movement puzzles instead of simply opening for you; after all if you're in a body it wouldn't be working for you. So something like them opening and closing at timed intervals for you to sprint through or something could have added some more.
But the visuals and sound were certainly an experience, making this the most immersive I've played in the jam yet!
I'd love to hear your thoughts on my game if you have the time :)
