Thanks for playing and your feedback! Sorry about the voices not being clear, they were pretty much a last second addition that I rushed into the game. Some of them didn't quite come out as I hoped in the final version.
Fair criticisms on the controls, I know those are wacky. And ya essentially everything (besides the shield) are meant to damage so they could all feel samey, though on the flip side all damage spells are viable. Fair point though since the energy is a bit strict you can't use as many as you like so it feels less like you are all powerful. I may tweak this some more, at least towards the end game. Thanks also for mentioning the Bilinear filtering. The game looks fine downloaded but ya they came out blurry online. First time uploading a project to the web and I didn't have much time to look into before submission. I'll check out the Bilinear filtering to see if that may be the cause.
Thanks again for trying it out!!
