I had a few spare kreds, so i decided to buy the exploding darts, but aren't very helpfull after you get the spike-o-pult upgrade. Maby sence the spike ball things don't explode, you could make them leave a trail of flames or somthing so you can ultimatly get what you paid for?
Love this game. You obviously base this game off of portal yet it was incorporated nicely. To me it was very suspencful at the end, when i saw the spikes coming, I restarted the level with the "kill" button an tried to see if I could shift out of it. Once I figured out there was no way to beat it like that i tryed to see if somthing like the spikes would just stop or somthing but they just killed me and it said I won. To me, the last level was the hardest.
