This was actually a refreshing idea, the rules reminded me of the Move or Die indie game, and thats a good thing! Making the player juggle with two characters was definitely a good decision, just trying to coordinate both hands was enough to make the levels interesting. I also got an I Wanna Be The Guy vibe from the game.
I got stuck in one level where you have two box and a path in the middle, I tried blowing up the boxes but the spikes in the middle were unavoidable no matter what, maybe I missed something? I do have to admit tho, I cheated a little bit with the Debug Mode just to try the next level, I was having fun :)
Most of the issues I can think of are probably pretty easy to fix, stuff like the radius of the bomb or some additional visual feedback when about to trigger spikes or spears (but maybe this will defeat the concept of the game a little?). Maybe also I clearer way of knowing how much time you have before dying when you're not moving, the bars werent really clear in my opinion.
All in all, a good entry, you can be proud!
