I managed to get it working perfectly and beat the game. I was constantly casting Level 3 spells without fail. I did cheat and screencapped the different laws of the elements between battles and had a copy of the spellbook open also. I recorded my full playthrough and uploaded it to YouTube to show that it picks up the microphone flawlessly (sorry I should've lowered the music volume, it's difficult to hear my commentary, so I've listed the important points below). Great job. This game pretty much does what it sets out to do but needs a little bit of restructuring and polishing.
Some constructive suggestions/critiques:
- Allow player's to skip the 60 second wait if they want to.
- Have a push-to-talk button so that players can talk without triggering spells unintentionally.
- Restructure the whole idea of the laws of the elements, since it is cumbersome for players to memorize each one between battles and it's very easy to cheat it.
