I remember you from the forum :-).
I'm happy to hear that you have if in your collection. I hope you one day will write me that you've beaten my highscore (Lvl 4, Points 806, Bombs killed: 47).
I tried to keep the radius somehow fair - but I didn't want it to be (very) small. Even if every bomb has the same radius I think as a player it is always a surprise when the bomb explodes.
But actually I think a smaller radius in most cases won't save you. It will just give you just one more second. At least when I die then it was cause the bombs trapped me.
Thanks for your comment :-)
