The Housing Issue has the beginnings of an nice, casual puzzle game. It's a fun idea for a Tetris variant and the background music and color palette give it a relaxing feel.
I could see a lot of ways that this could be expanded by adding more block types or having to build around obstacles. I like that you're given an option of three blocks to build from; however I found myself defaulting to the line pieces. Given how high you're building, using the S- and Z-blocks feels a bit unfeasible. I actually found them harder to work with than the ice and bouncy blocks, so I think they should probably be given a higher point value. They could be more usable if you were able to nudge them as they fall or rotate them so that they can fill in gaps more easily.
Those are just some thoughts for the future. Over all, I had a lot of fun with this!
