Combining tetris and platforming has some interesting implications (making sure you can platform up the blocks and, not blocking paths) though placing shapes and platforming is too unrestricted to be particularly challenging but it does work nicely as a chill game currently.
i felt that it plays quite slow due to time it takes to place blocks(The transitions take awhile and having pieces fall from the top might not be the fastest way to place the shapes)
i think being able to zoom out or look around while in run mode might be a nice convenience
