The smiley needs to change direction and move a lot farther. It's a good start and isn't just a piece of complete rubbish thrown together but it needs more of a pull. Maybe if the smiley bounced of walls and the floor?
There's a huge problem with this game. You just halt your tanks and helicopters just in reach of the right edge and reinforce them every now and then. Easy peasy and boring.
For this one game I cna't get Kongregate to connect. The light remains red. I gave it 3/5 for simplistic gameplay though that really wasn't challenging.
OK, Boss tips.
1. Forget dragons. They're just a waste of money. Angels cost double but protect wizards, do double damage and last twice as long.
2. As long as an angel is fighting the boss wizards can attack without taking damage
3. A continuous stream of hobbits is cheap and it will almost completely prevent the boss from moving.
4. Make sure the arrows hit the boss but don't hit your own people, especially watch where the arrows are fired from because they can hit angels there.
5. Use specials as soon as possible
6. Make sure you've got the barrier etc up before you fight the boss.
I beat the last level without taking damage so I hope this helps.
I gave it a 5. I personally don't play or particularly like RS but it does no harm to Kongregate and it's a much more professional than a simple flash game.
The missions and the humour are great, the fact that you can only seem to shoot people in the head isn't (it doesn't wound) but the inventiveness of the missions make up for that. A bit easy though.
