Does anyone else find the climbing training really frustrating? Especially after about level 90, it moves so fast that its super hard to gain more than 5 levels in one run i find, while in the others its easy to get 10 in one training session. This, combined with the keys sticking on my computer makes it nearly impossible to endure :(
this game is very annoying in that its so hard to stay in the freakin field. it seems that every time i am about to make a kill i fly out. this is a major problem. it also stops me from getting the bubbles i have already earned. i wish it was like in arenas where you cant leave until you have killed all the enemies.
Easiest (But rather long) way to get the badge with 2 players: Select the 4 Castles Map on Nightmare difficulty setting, turn off Devils, Collisions and Friendly Fire, barricade one of the corridors with barrels in a kind of box shape so you can run back into it if one of you is killed (the zombies wont attack the barrels), then stand side by side in the corridor outside the "box" of barrels and use your pistols to shoot all the zombies. This works none will get through but it requires a lot of patience. This could work with one player if you use a shotgun and keep refilling your ammo with the boxes that will appear in your barricade if you use a corner but i have not tried it on my own and im pretty sure it wouldnt work. Plus if this comment helped you get the badge.
Finally beat it after about 530 deaths. This is a good game and i dont care that it is a rip off from the mario ones because they are all fun to play. I dont really like the name "The Unfair Platformer" since games dont really have to run by a predefined set of rules, it's up to the developers to make the rules of the game, after all, it is their game. Maybe "The Ultimate test of platforming skill"... or patience.
sowelu it says if you had read on the sign at the start that you can turn off the music by right clicking it also says it in the controls thingy in the game tab
