[SP] Funk Tank
Drive It!
A funky tank that fires gnomes and lasers.
Great consept but it doesn't work that good honestly. It sure is fun driving a tank and shooting gnomes! Hardest part of the puzzle was finding out that you can leave the tank and hitting those last turrets. Aiming was really annoying because there seems to be a little slice of vertical space in the middle you can't shoot at and all of the enemies seem to be in that area. Also driving up the hill was pretty annoying because the tank didn't have enough horse power.
Biggest bug I found is that if you hold w or s and then press e the tank will keep going. This will get you easily stuck. Also when you drive under the squigly doorway after the ramp there is a spot where all props become invisible. I'd guess that is an optimization mistake or something? Also if it could be possible put the very last death field little bit further from the button because I pressed the button and instantly died the first time.
It has flaws but sure is an impressive map and really creative idea. Great job!

Cheers Shakky, thought I'd ironed most of those out, but I'll get an update ready in a bit 
So while most of the world is churning out identical loaves of white bread, sicklebrick is making brioche. This was a lot of fun, though, like Shakky said, the aiming kind of sucks. And I have to admit that I cried at the end, even though I knew what was going to happen.
Updated, thankyou for the feedback sexypeople, your cookies are in the mail.
Unfortunately, I can't fix the laser aiming due to the laser snapping to horizontal when it's within a few degrees. In such cases I reccomend an explosive gnome or vehicular turretslaughter.
If anyone has any ideas for that one, I'd be very grateful. Cheers
Edit: Forgot to mention, thanks to marKiu for the theme idea, and whoever I stole the audio samples from for the audio samples
I just did a Least Gnomes run of your map. I did it in two gnomes! But I got a lot of turrets stuck under the wheels and, man, they are hard to clean out.
Originality: 10/10
Execution: 5/10 (system constraints are entirely to blame here)
Hilarity: can not effing compute. *Squeak*!
Do you get a Steam achievement for a gnome-free run?

Very clever. The tank operation is a bit dodgy....but fun.
Thanks for creating....
Oh noes, you guys are getting it all wrong. More gnomes! We have a surplus and they're very expensive to feed & clothe.
I'd like to have made the controls a bit better, but like HMW said the system was a bit limited.
For example I deffinitely wanted the wheels to work on buttons, so I couldn't use prop_physics with some phx tires (or hide spheres inside prop_physics as the collisions would be way too wide for the wheels). This meant no mass override for the wheels, and no friction control.
In any case, I couldn't get any of the unlisted high friction materials like 'jeeptire' in gMod to work either, so the wheels were always gonna suck. The body too had to be built from 4 separate sections, as parenting disables any sort of attached physics constraints - leaving us with a slightly wobbly body. Then of course there's the laser snapping to horizontal, andthe func_tank aiming entity having to be slighly in front of the player :
Anyway, I fully intend to revisit this at some point, but for now, glad it's being enjoyed. Cheers for the feedback
Without a doubt, the most original thing I've seen. Fan friggin tastic!!!! Would be interesting to see this incorporated into more maps. ) Hint..
