This is a great game-- innovative and fun. The only thing I suggest is adding some sort of graphically representation of the explosions. Having the explosion-force be invisible is too passive-looking.
it reminded me of totem destroyer and perfect balance, both pretty good games so i guees that makes this game not so bad itself. good basis for a game, aside from the puzzles on each level it needs more to it
i got bored very quickly, its too much like BoomBot
The thing i missed most was explosions and sound effects, add those and it will be more enjoyable!
I loved to play this game but i can't get past level 23 since the small block with chain attached on it keeps exploding apart instead of bouncing up to the tower no matter where i place my bombs or using other blocks. The physics in the game need a rework because sometimes the blocks 'flies' differently even without moving bombs.
I found another way to set the bomb timer, the green bar that represents the time in the bomb timer console can be moved with your mouse like you do with a scrollbar.
your phys engine is wack.mess around with it a bit more before you make a game based off of it.
