Really nice use of the theme for the time representing your health and the time remaining! It's simple, but addictive to play. I think the boss balance could use some work for the second set because they teleport so much that it's extremely hard to kill them since they will go somewhere random, usually all the way across the map, so there's not enough time to chase them down. Because you're on a timer, it wastes too much time plus the amount of health they have compared to the amount of damage you can do at that point is pretty large. I'm still thinking if it's better to have Kronii always attacking since I'm always holding the right mouse button and at that point, there's no reason to have a button for that. In any case, good job!
