Amazing work! The game has a really fun feel, and the effects on the intro and the abilities, plus the music, make it feel really premium. At first, I thought I wouldn't like how slow casting spells was working, but I found that it really made me feel like the wizard/necromancer rather than some kind of magical warrior. I've gotten to wave 24, and I don't think I can lose at this point. The upgrade to disable the summon cooldown is really satisfying, but it might be a bit overpowered. You've put in so many cool abilities, but I didn't really need them once summoning got enough upgrades. None of that really changes how good it just feels to play though. Even though I don't think I can die at this point, I'm tempted to just keep playing anyway. Awesome stuff!
