So like yeaaah, Mutant Mudds... odd little title but defintely a great one for someone craving a dose of ultra precision platforming. At first the game feels really cumbersome and clunky because let's face it, it's not supposed to play like New Super Mario Bros... You won't be running at top speed and almost sliding off in to a chasm only to do a triple backflip in to a ground pound... nope, none of that here. You walk, you hover, you jump, you shoot... bout it.
This game is very... let's say, square.... or rather pixel perfect... everything works in blocks, rows and lines... so if you keep that in mind when you're traversing the trecherous one hit kill spike traps, you'll be better off. The game is intended as a grueling challenge for older children, around the age of like 10-12... and for someone of that age, I can see this being incredibly frustrating and they will surely deem this game unbeatable... but it's really not.
Don't expect "Impossible Game" or "Super Meat Boy" quality challenge here is basically what I'm saying. If you can tolerate playing most web based flash games for longer than 15 minutes, this game will proove only an above average challenge for you. You shouldn't at any point want to throw your controller at a wall... if you do, then you have no patience because that's all this game really requires.
Sure there's a time limit for speed running levels but that's more of a tacked on thing if you're craving more Mutant Mudds after you've collected over 4000 objects... and if you are, please seek some help. After the inital batch of normal stages and ghost stages I cringed at having to do 20 more stages with good ol' grannie but I actually found those stages the least frustrating after I had finished a few.
All in all the game is good, you can finish everything in roughly 5 to 6 hours which is decent for the price. Other less experienced platformers might take a bit longer but I can't see this game taking you more than 10 hours.
Side Note: There's an exploit where you can stand on the very edge of spikes if they're on a platform, so use that knowledge to your advantage if you're having trouble finishing some of the harder areas.
