I don't know if this was a one-off thing but when i threw the plane bacwards, it unfroze after a while and my plane was gaining distance while off-screen floating. I got the flying low and supersonic achievements like this because there's no wind resistance :D
There's a very annoying glitch which sometimes occurs when using Rigid Joint. A white line comes from the top left corner (only when paused) and when you unpause the thing you used the joint on dissapears. When used without pausing it just dissappears. This only happens when try to fix something in place, not attaching. Keep this comment alive so that the developer can see it.
I don't think the camera is too bad but the levels get really long in later stages and slightly repetetive. It's still a good game though, great concept. 4/5
Wtf initially this game was ok but on level 33 the bloody cannonballs kept hitting the platforms this zombies are on. the tutorial also isn't very good and its really vague.
great game its a good unique take.
my best strategy is to get a sniper tower at the start, upgrade it as you go through the waves until its max. then add an electro tower and upgrade that and a machine gun turret and upgrade that.
then you can get pretty much anything, a poison and ice tower is a good option, th en you can get heat towers but not flamethrowers. missile launchers can be added but arent necessary.
