I like this! The physics is very smooth when dropping the blocks! The instructions are also very clear which is always great! The blocks when being thrown are stopped on the left & top of the screen however not on the right. Some blocks can be thrown through the floor if they are at a fast velocity. Occasionally the blocks can stick at the top of the screen too.
If you're looking into adding more features into this game, maybe having an option to add some more blocks could be interesting?
Great job on this so far buddy <3

Only 3 blocks? Now I can't get myself cancelled for a stupid 9/11 joke!

bruh is that it
