How about some weapon specific abilities?
something like,
Dagger +%crit, Sword +%dmg, Bow +%atk speed(aka balance), Crossbow +dmg etc. etc.
Also I think you should make a "defence mastery" by taking out the +hp from combat mastery and replace it with balance or protection ignore.
and make the defence mastery increase hp, defence and protection.
1. Speed up button
2. Move/sell weapons
3. No limit to how many weapons you can have
4. More levels (aka more "special" bunnies)
And you got a 5/5 game with a longer playtime.
Yeah the armageddon and the Drill Instructor and nitroglycerin perks need to count towards kills for the equipt weapon, or maybe a way to turn them off?
work a bit on the controls and give a bit more fuel.
As for the controls.. make the plane hover a bit longer and make it so that the chopper always tries to stay level, aka if you push forward it and release it will slowly level out.
