For those having trouble on level 5 (with these lines of creeper): It takes a while but isn't that difficult. I took a few makers, charged them and released the anti-creeper just next to the lines of creeper. Add a lot of blasters and launchers (I think I used 10-15 each) and then just wait (repulsors are useless here). Of course you should have enough reactors to support your weapons.
Is there anyone who got the hard hard badge and would like to share his tips on how to beat level 15? My best was getting Raze Soldier down to four lives. But my teammates, the time limit and the fact, that this guy seems to be evading you on purpose (at the end I sometimes run around for a minute without seeing the Raze soldier) make it seem impossible to actually beat this map.
Aside from the "red tint on zombie territories" which Ficknmaniac already mentioned I would add something else: When you click on a character which is carrying an item it shouldn't read just "10" for the skill affected but "9+1" so you can see if the person needs this item (because 10+item = 10 because 10 is the max level)
Two suggestions:
1. I guess thats intentional, but I get the feeling that mines go off when you get close to them (but you're not touching them). A bit annoying.
2. You should always see how much health the enemies have. Or perhaps add it as an upgrade (I'm not very far yet so if there actually is such an upgrade nevermind ;) )
Good game. Some suggestions:
1. Autosave (and for now a clear hint that no autosave is in place)
2. When enemies miss they still can poison, silence etc. one of your characters. Doesn't make sense to me (although that doesn't have to mean much ;) )
3. More explanations. For example what stat does affect my skills? Does Magic enhance the flame sword or does the damage output of this skill depend on Attack?
Great game. Found a but, though: I opened the inventory, used a bandage and got the message "Achievement awarded. You can find the Battle Axe in your storage" which caused the game to unpause in the background. Of course, I was killed.
I think you should be able to rate the song you just played so you can tell other players if this song is suitable for this game (5/5 would mean that there are enough jumps on the (race-)track).
Great game. It would be fun if you could see what other players scored on the song you just played. I don't know if that possible because everyone names their mp3s a bit differently... but what should be feasible is a search function for songs other people played to. This way you could search manually for an artist or a song.
I think you should warn the player of new enemies, at least of those who can kill you. I made it to Tier 19 in my first try and I was standing in the right corner when suddenly this rolling shape squished me.
