lol the weight upgrades are fine but maybe you should add some more ammunition upgrades and maybe some other siege weaponry that you can eventually unlock for fun...
Ammunition upgrades:
Burning
Explosive
Spiked
ect..
Siege Weapons:
I don't know the name but the giant cross bows... lol you know what I mean
you can also have different ammo for that too
ect..
Oh and it seems like the walls NEVER break no matter how much you damage them, that should be changed too.. they should break into pieces
Pretty good game. Needs some work though. More upgrades as stated before and a level selection would be nice. The humans need to die more easily when walls fall on them and such. On the first level I couldn't imagine even hurting the king. I made the entire building come down on top of him and he's fine. Also I once managed to get a human to spin through the air and land on his neck, instead of snapping his neck and popping his head off he just bounced a little. So a bit of physics tweaking with the health of their body parts and such would be nice...
pretty good game actually.. I enjoyed it a decent bit. I have a suggestion though to reduce the amount of grinding needed (it's a single player flash rpg.. you shouldn't need to grind to much). Whenever you clear an entire screen of all of its faction you should get a large bonus in xp and in renown. So for example if I manage to have all of the Alliance on one screen dead for a second so that there's no one left to kill I should automatically get like 10 kills worth of the xp that THOSE particular units would give me and 10 kills worth of renown (both negative and positive) for those particular mobs.... would reduce the renown grinding towards the end. I'm currently sitting here needing to grind about 2000 renown for both the Mercenaries and the Shadow Runners.
