I just made a Gladiator and a Pirate for my upcoming game, Pixel Kingdom! This brings the total of units to 15 for launch day. Here's some info on what I've got so far I'd love to hear your ideas! Let me know what you think the Pirate and Gladiator should do. Btw they are unlocked with the following achievements:

Here's some gameplay:

Love the art style, great work sofar.

Here are some ideas:

sorcerer - summons imp(distance attack)
archmage - rain of fire
druid - roots (enemy hold in place)
shadowknight - drains enemy, heals himself
juggernaut - "rolling" attack

You totally need a dragon unit. :D

Sappers - Move them forwards below ground - pop them up behind the frontlines

Suicide bombers - run and blow up

Falconers - ranged unit using falcons to dive bomb enemy troops

Trappers - ability to lay different types of traps from bear traps to pit traps

Golems - achievement unlock - heavy troop

Heralds - banner carriers who are not combative but provide combat boosts to nearby allies and/or combat nerf to enemies

Trumpeteers - as per heralds but music

Drummers - as per heralds but drums

Bagpipers - achievement unlock unit - as per heralds but bagpipes

that's all I got for the moment

How about something to alter the style a bit. like Fireball. Not a character, so you don't get a chest or units to the other side, but very powerful attack. hits the first unit it comes across from where you send it, including yours. Good to use if you are overwhelmed, but costs too much to use otherwise. Similarly, you could also have a catapult, which takes a long time to reload, but will essentially roll a bolder down a lane, knocking anything out of its way that doesn't have the ability to switch lanes, like the bat.

As for pirate, perhaps the pirate jumps over, or goes around, the first enemy unit, and goes straight for the treasure. a good character to use if your low on money, but otherwise not heavily armored.

Gladiator. Perhaps the gladiator will jump lines to take on something else when its line is clear.

Perhaps another unit might be a Shield Barer, who essentially is pushing a really large shield across the map. Moves slower, and takes very little damage, but units can get right up to it, and also enjoy the shield bonus when they attack.

Minor Sorceress - can't take on anything in battle, but anything in its path below a certain level will join your side and begin marching the other way to attack with you.

Assassin. Runs up to a certain point. Burries itself (you see little eyes poking out of the ground) Once the enemy passes, it pops out and attacks from behind.

Another thing would perhaps be out of game character upgrades. I.e. when selecting your characters, perhaps you can drag them to a particular editor tile, which pulls up a larger view of them, and gives you the ability to spend on upgrades. I.e. Heal faster, Heal others more, Attack more, etc... even just one special bonus for each type. like archer might get Net and Rotate. Net allows archer to shoot down Bats in one hit. Rotate allows them to shoot another line, if the enemies in that line are closer.

Perhaps a Super enemy as well, that gets its own hitbar. like a Giant.

Perhaps caltrop dropper. (little spikes left on the ground behind them) If an enemy steps on it, they take damage, bounce back and that caltrop disappears.

Another might be a Ghost Spy. They are transparent, the enemies can't see them, unless they are unnatural, like ghosts and wizards, so for the most part the ghost spy will cross freely passing through enemies.

Perhaps with the role of a spy, you can start getting hints to where units are lining up to get in, and possibly what they can do.

I don't have much of a suggestion to make here, but I really love the art!

Keep it up!

Thanks for the great ideas and compliments!
