yeah, this no longer works because the supernova link it gives you uses chat.kongregate.com instead of www.kongregate.com and this version of the game won't play on any other site except www.kongregate.com
I tested it with a throwaway account and apparently the exploit isn't as easy as I thought, but for most people it would be easy enough to rack up a huge amount of microtransaction currency with it.
Whatever patch added badges and the Black Market ruined the game. If microtransactions weren't bad enough already, the ads force you to wait 10+ minutes or delete all save data to get back to a decent number of microtransaction currency per ad. There is an exploit that allows you to get a lot of microtransaction currency with very little effort, but it requires knowing how to do it in advance. Also, I noticed that some other things have been changed for no good reason. This made me regretfully give Learn To Fly 3, previously one of my favorite online games, a 1/5 stars. At least the original version on Lightbringergames' website is the same, which makes me think the new patch was Kongregate's idea.
And what "other things" have been changed for no good reason? As for microtransactions, if we're ever gonna see a LtF4, it's because I will have been able to support its development. Otherwise I'm getting a regular job. Around 5,000 work hours brought in less than a year's salary so far.
Here's a theory to explain why you die of explosions immediately when you run out of fuel: The player's robot (JC for John Carbon) runs entirely off of an internal combustion engine and an auxiliary battery. Unfortunately for JC, the auxiliary battery has crossed wires and will short circuit if it ever discharges any electricity. When you "run out of fuel"(you haven't actually ran out, just gotten sufficiently low), the auxiliary battery activates, sparks get too close to the fuel tank and item storage, and the remaining fuel and flammable cargo go up and cause a huge fiery explosion. This being a robot and electricity, everything in this chain reaction happens within less than a second of getting just a bit too low on fuel.
I just want to say that it's only this instance (Kongregate) and the HotAirRaccoon site instance that's bugged. It works perfectly fine at http://armorgames.com/play/7494/kids-vs-ice-cream , go and play it there. +1 to keep alive.
Bonus Shop carries over between saves, so if you accidentally autosave over your old save you will still have both your medals and your Bonus Points, in fact it is absolutely necessary to get some of the Bonus items to get the hard badge. Just saying this because I saw someone comment that they accidentally autosaved over their story mode bonus shop and that actually isn't possible to do by accident.
