wow! my favorite out the 15 or so i have tried.
I suggest increasing meteor count in later rounds.
I also suggest placing in some sort of round carry over health for the blocks. During my play through I found myself with plenty of stone and metal blocks. I liked making the structure, so having a high count of the blocks was fun. I feel like the the best part is teh core of getting resource to place, and managing them based on incoming angle. Blocks having health bars and taking damage each turn would add interest to placement management.
I feel more metoers more better.
One bug is you can block incoming meteors by holding a block to place it in its path. when the strike occurs (round starts) the block will fall momentary, then the meteor will strike it.
great game. cant wait to play again once more fleshed out.
