Hey, I had a good time playing this, even though I'm not sure I met the minimum requirements suggested. Really liked Elara's design, and really liked the effect of the double jump - I was double jumping around the whole map just to see it more often. There were a couple times I think I interrupted some dialogue by moving too far forward a couple times, which was a little unfortunate. There were also a couple times when the text would scroll all the way past the text box and I wouldn't be able to read it anymore.
I think my only gripe with this was the section with the crystals. The rest of the game was pretty linear and platforming light, so it took me a while to figure out where I was supposed to go to find the crystals, and the way I took to get to each of them made me feel like I was doing something I wasn't supposed to be doing. I also don't know if I was doing something wrong during the fight with King Alfred. He was taking very little damage overall, and he eventually starting moving way too fast for me to catch up with him. I ended up having to hide in the tunnel where the Water Crystal was to avoid him and the monsters he was summoning.
After that I got stuck in a white void after going in a portal, but Hayley said it was one of the lighting rooms, so I figured that's where my hardware limitations fully caught up to me. I don't know how much of this was the lack of the missing requirements, so feel free to take most of this with a grain of salt.
All in all very nice work!
