Thanks for playing and your feedback! There are some bugs in the inventory system, but I'm working them out. You still should be able to complete the game to both endings even if you can't always click on your inventory properly, but it is annoying and I'm eradicating that issue right now.
As for the speed of the character, there's a "speed" slider under the Settings icon in the bottom right corner. You can jack that up and scoot him about pretty quickly. Believe me, if I'd had to test the game at regular speed, I never would have gotten it finished!
Thanks again, and I hope you get a chance to see it to the end!
