If feel the same, it took me over 10min to finish it... but i had fun.
I had the idea that the flamethrower could only be used for a certain amount of time,and slowy overheat. But that would be realy annoying: you would get stuck and have no way to move, get overheated midair and fall into spikes, cant get as fast as you want. That would make the gamplay worse so i didnt implement it.
