BUG: the select-stage button only allows you to access the last-*passed* level, not the following one (passed level 24, started on 25, went back to the menu, now can only get into 24 again)
would be nice to be able to see the friend's Special (if any) when the friend is selected - I have no idea whether to upgrade the skill or not on the bastard carrying a bazooka, since i can't even see the weapon list without buying an extra (unarmed) friend
also pro-tip: don't bother shooting dogs, guys, etc - save your 6 measly shots for those large collections of boxes and such. (you'll need at least 4 for them, I flew over the rest)
tricks = kinda weird. you get them for crashing into things from above, from staying airborne for some time, etc - but it's not really consistent enough to tell why. with *all* upgrades i just barely managed to reach the end, with my last ounce of strength - i have *no idea* where i got the energy to then punch out all those bozos afterwards.
that slew of notes on top actually blocks out the top row of... er, blocks, so it's hard to see what i've touched already. also 10% of the achievements completed in the first 3 seconds of the game? might be a bit TOO easy.
Why do you put those turn markers on the *outside* of the curve, where a skidding car explodes violently, rather than on the *inside* where they're harmless?

Now the weapon list is visible when no friends are selected, or only unarmed friends are selected, that should do it :)
