Wow, just an amazing amount of content. Don't know how you do it! :)
I played for quite a while, got over my fear of those tall Groot like monsters, definitely hits the wild card.
I'm currently on the first portal level. I read the instructions (can't get them back up though) and think I needed to do something with the mouse wheel while casting the spell? It would be handy if there was a way to get the instructions back, or even just a spell book (maybe I missed it?).
I'll have to come back and try progress further (looks like there are more crazy things to come), hopefully I've just missed an ah-ha moment to pass that level. But yes, very impressive I have to say, love the glow effects! And implementing portals in 9 days, just crazy! Well done!
