------------------------

-- version 0.4

------------------------

-- removed some old code/comments

-- removed both shell and mortar as the primary and secondary weapons

-- the primary weapon is now an explosive(barrel)

-- added support for picking up barrels scattered about the map (backspace)

-- added support for dragging around mines (enter toggles on/off)

-- added support for primary fire being onAttackUp

-- added a trail to indicate when the player has 5s or less left to tumble

-- updated showmission to reflect changed controls and options

------------------------

-- version 0.5

------------------------

-- changed some of the user feedback

-- i can't remember??

-- substituted onAttackUp for onPrecise()

-- brought in line with new velocity changes

------------------------

-- version 0.6

------------------------

-- reduced starting "ammo"

-- randomly spawn new barrels/mines on new turn

-- updated user feedback

-- better locs and coloured addcaptions

-- added tag for turntime

-- removed tractor beam

-- added two new weapons and changed ammo handling

-- health crates now give tumbler time, and wep/utility give flamer ammo

-- explosives AND mines can be picked up to increase their relative ammo

-- replaced "no weapon" selected message that hw serves

-- modified crate frequencies a bit

-- added some simple kill-based achievements, i think

------------------------

-- version 0.7

------------------------

-- a few code optimisations/performance tweaks

-- removed some deprecated code

-- fix a potential spawn bug

-- improved HUD (now shows ammo counts)

-- improved user feedback (less generic messages)

-- colour-coded addcaptions to match hud :)

-- base tumbling time now equals scheme turntime

-- tumbling time extension is now based on the amount of health contained in crate

-- new mines per turn based on minesnum

-- new barrels per turn based on explosives

-- added 2 more achievements: barrel eater and mine eater (like kills, don't do anything atm)

-- slightly increased grab distance for explosives/mines

-- slightly increased flamer velocity

-- slightly decreased flamer volume

-- added a flame vaporiser (based on number of flame gears?)

-- give tumblers an extra 47 health on the start of their tumble to counter the grenade (exp)

-- refocus camera on tumbler on newturn (not on crates, barrels etc)

-- increase delay: yes, yes, eat your hearts out

-- commit log

-- Better HUD

-- Allow more user customization

-- Bugfix for new gear spawns

-- Performance tweaks

-- Variety of small gameplay changes

------------------------

-- version 0.7.1

------------------------

-- redraw HUD on screen resolution change

---------------------------

-- some other ideas/things

---------------------------

--[[

-- add better gameflag handling

-- fix flamer "shots remaining" message on start or choose a standard versus %

-- add more sounds

-- better barrel/minespawn effects

-- separate grab distance for mines/barrels

-- [probably not] make barrels always explode?

-- [probably not] persistent ammo?

-- [probably not] dont hurt tumblers and restore their health at turn end?
