The second to last level is horrible. Twice in a row the first guy through moved the boxes so that nobody else could pass. Losing is okay, being force, repeatedly, to quit is not okay.
I agree with tenkachima, you get way too little xp per race. The user created maps have almost no racers, so it's even harder to get XP. It's a lot of grinding to get to the last level.
Do the attacks list anywhere whether they are short or long range? I feel like I'm guessing what range I should be at while I'm learning my characters.
This game gets extremely repetitive. It needs more changes along the way, like new types of grenades. More enemies types sprinkled throughout would also be a big help.
There *really* needs to be a pause after you lose. I'm clicking to fire, but I die and click on something that ends the game before I even realise the game is over.
itsAweirdOne, it's not particular levels. You have to max out a group of levels to unlock a hidden level. If you want to get all the hidden levels and get the badge, you'll have to get shining frames on every single regular level.
Unlocking secret levels isn't random. You have to get glowing frames on a *group* of levels. Once a whole area has been maxed out, then the secret level for that area will appear. The easiest way to do it is to beat the whole game, then go back and use the 3X speed to power through the levels again.
The easiest way to get the glowing frames is not to worry about them at all until you've beaten the game. By that time you will be so powerful that you can replay the levels with the 3X speed button turned on and blast through everything with ease.
Vesnator, you have to do a whole bunch of glowing frames to unlock a secret level. If you do all the levels that are in one area, that will probably do it.
To beat the epic level, save up some mana before that last boss. You'll lose a bunch of mana when he gets to your hut, then he go back to the start and you can shoot at him some more. Click on him and the info screen will tell you how much mana you have to have to survive him getting to your hut.
