Played slow on Chrome (sound played, but slowed). Played fine on Safari, no sounds heard on Safari.
The key mechanic is a fun idea, using it to reach places (although I got stock in the room with the first spider for a bit, but passed it with the pixel perfect jump needed between platforms). Felt great to figure out how to use the key to climb up.
I didn't read the game description other than controls, but started to enjoy the game more after the vine climbing key enhancement.
(felt weird walking off a platform then seeing the character hover, due to them latching on to a vine. Not sure if there is a sound cue for vine grabbing, but threw me off a bit). The key enhancements were great to discover and fun to use and solve your puzzles.
You have excellent level designs planned out to teach the player how to use your key enhancements; How to navigate levels while tilting the key, and levels designed well to teach how enemies work.
Also, my favorite enhancement is the spiked key, because fuck those rats. Got up to the gauntlet level, but stopped playing with the narrow drop with the spider, couldn’t figure out how to pass that part.
Great Game!
