Ok, i completed it. The take on the theme is quite clever, and i loved the twist on mood and story (it's subtle but it's there in form of power ups descriptions, very well implemented! What happens if i choose no?).
The audio is too annoying, too loud i turn it down instantley. Maybe it was for setting the mood but it's was too much.
There's a bug that makes you need to click launch twice and if you already place some blocks...puf! the blocks are gone and you need to start again.
For all the game I didn't strategize anything i kept spawning big blocks. Maybe i don't get it but the others blocks feels only like a plus but not a necessity.
That said you've found a quite fun micro-loop in the spawning blocks. It's very fun to do, you can work on that.
