Yeah, you are totally right. We had originally planned to have 3 random upgrades pop up at the end of each wave, where you would choose which one to use to upgrade either your player, your relic, or receive a random power up. Also we wanted to dress up the level much more, which we in the end never got around to do. Thank you so much for the nice comments. I've put your game on my list to check out, but I didn't have a chance at work to download it yet.
