As you all can tell this is very WIP, I posted it to get suggestions. So, things I plan to add: Visible health bar with skulls. There is a speed variable that effects Vortex, and bloons move even slower at base, but faster the higher tier they are. Getting a skull will freeze everything on screen basically for 10 seconds, letting you get tons of damage on the boss during it. He may also take extra damage during this. Placeable towers will cost money, farms will exist too. There will be a way that bloons can target "First," The bloon in front be marked as first. This will help during the normal rounds. Vortex spawns on round 1 with 1000 Health, round 40 with more, up to round 120. Improved bloon sprites will come soon, and more bloons, up to a bad. Currently the bloons really suck but I think I know a way to do MOAB health, and eventally BADs. This is basically a demo
