Well made addition to it's genre. When I first encountered the broken cables underground (wasn't using dynamite at the time), I almost got mad because I had no idea what was going on. After I got the shock protection though (get zapped 5 times) and started using dynamite for scouting ahead, the game was in the bag :) 4/5
I'm sad to say this as I'm not usually the guy who points out flaws, but this is yet another sad attempt at copying the good ol' fun that is the Java-game Trials.
Pretty good, needs a few adjustments though in my taste:
Less choppers... I mean, you hit 3 choppers for every bomb you hit.. It's annoying as hell and just takes up time.
250k for the last cannon? That's a LOT, even with all the other upgrades purchased. And while we're on that subject, why would I want it? I won't be able to keep the speed from the launch for more than a few seconds anyway due to all the choppers.
Spell check is your friend!
