Thanks for playing it and leaving your feedback!
It was in the tutorials as a brief text, should have added image .. a lot of people missed it :S
Yeah, the shield was designed with that in mind, wanted to have enemies shooting at you etc...
Spent a lot of time building the "foundation" for the spell invocation that in the end didn't make it to the game, The vision I had in mind, is that you could interact with the environment, a tree for example, draw some sort of pattern on the tree, and its roots come up and whip the enemies or something.. make meteors shower on large enemies groups .. etc etc.. this was of course proven to be way too ambitious for 48h.
As for planning I failed 50% I guess, I left time for adding sounds, and game level.. but what I failed to plan, was my own energy... LOL
With 3 hours left, enough to at least add some sound effects, I was struggling so hard to stay awake.. so just made the game level really quick and submitted .. :P
