This looks like a bigger version of Flood Runner 3 made out of notion that if one made it bigger, it would be just as more awesome. It actually turned out monotonous and boring. And what is even more disappionting, you cannot rely on your gaming skills now as there are now things that strike you just as you pass by. The controls are now sensibly less responsive, which adds to the odds of landing on something that hurts. And last but not the least, the achievements have become pointless. If in FR3 one really had to survive a long run in order to get something to gold, now it boiled down to just replaying the games until infinity. You don't expect anybody to kill 800 similar monsters in one run, do you? Or kill 40 similar giant mosters, although we all know that to kill five in one run was a serious achievement in FR3? By the way, these figures are thresholds for silver, not gold. To summarize, this game is way too big and dull. Whatever, nobody will really read this review 5 years down.
