    • Slimes
      • The game has a variety of slime types.
        • Green slime take one shot to defeat and are worth 5 points each.
        • Pink slime take two shots to defeat and are worth 10 points each.
        • Orange slime take four shots to defeat and are worth points each. Orange slime also shoot fast-moving fireballs at the wall.
        • Blue slime turn to ice when defeated.
        • Yellow slimes are strong and move quickly like rabbits.
        • There is also a purple slime, but I kept losing before I got to it. 😉
      • Large slimes
        • As you advance through the game you not only face more slime types & stronger slimes, but you also fight larger slimes.
        • Large green slime turn into 2 smaller green slime when defeated.
        • Large pink slimes are similar to the large green slimes.
    • Play tips
      • Upgrade strategy
        • Try to avoid using defensive upgrades until you are at least a half dozen levels into the game, so that you build up strong offenses.
          • Your enemies get stronger and faster as you progress through the game.
          • When you upgrade your offenses you shoot more frequently, further, or more powefully that round & for all subsequent rounds. Whereas when you upgrade your defensive wall it still gets chipped away at on each round.
        • Early in the game it can make sense to upgrade shot amount, cannon update, shot damage, and shot speed.
        • As you get a bit further into the game unlocking other cannons makes a lot of sense. If you have multiple shot amount or enhanced shot damage activated then it can make sense to unlock the other cannons sooner.
      • Firing on fire
        • When you get to where there are fire-shooting slimes it is good to have 2 or 3 cannons enabled so that you have a spreadshot effect and can take out some of the incoming fire while also being able to hit slimes.
        • The fires move quickly so it is important to take them out immediately as they do just as much wall damage as a slime does.
      • Prioritizing slimes
        • If you can’t keep up with slimes then it can be best to skip a strong slime and focus on taking out weaker slimes so that you minimize the number of slimes which hit your walls.
        • If a slime is advancing in a position where there is no wall then you have to take it out or you will lose.
  • Target Audience
    • The game is suited for players who like tower defense shooter games.
    • The game has no adult themed content.
