I think this game definitely has legs!
I would love to be able to navigate over the walls to quickly get to the other side. And a way to refill the teddy blaster would be nice too.
Maybe some sort of indicator that the teddy bears can pass over the wall, just not the character? I kinda assume that if I can't get past an environmental obstacle, other things won't either.
For the teddy bears respawning, just some text somewhere like "Don't use teddy bears too fast, You don't get new ones until next round!" would be plenty of hint I think.
