The first thing you notice in this game are the beautiful graphics. I love how the floor reflects the effects. The music is nice as well. I don't like how the walls appear right in front of you, I think they should be waiting in the hallway ahead. I also think there shouldn't be a cooldown for the spells, because when there's more than one socket with the same colour, it's very hard to tell how many of them you've filled.
All in all, the game was pretty good, although quite repepetitive. Keep it up!
