Barbarians at the Gates

I like this game. But it could be great if you added some way to heal Archers and upgrade them.
If they were a bit cheaper, towers, it would be great.

Gold mines should give exponentially more money, based on wave number and/or number of other gold mines, and act as a multiplier for amount of gold gained from slain enemies. That way, the 500 gold is actually worth it, instead of having to endure 20 waves just to gain the money it cost to build one, when the money could instead have been invested in better defenses.

Barbarians are worth too little and the walls and archer cost far too much. The mines don't produce enough to build defenses to keep up with the increased number of barbarians every wave.

1. Units are too expensive considering the amount of money you get from slaying a barbarian,and the amount you get from a mine
2. Units should be upgradable or at least we should be able to sell them
3. How long does that wizard need to load his spell o.O
4. Barbarians get all sorts of upgrades (like the armor) and i was stuck with 3 archers and 2 cannons, died not long after that

overall its a cool game, just a few upgrades would make it more enjoyable
4/5

nice concept, but things are too expensive, the 'units' die too fast (i mean, how on earth could an archer who is on top of a wall, get killed by a clubman without a ladder) and earning money goes way to slow. i respect the man who can complete this game in hard mode without using a bot.
