For a first solo dev project, it's admirable! Finishing anything at all is already a major accomplishment, and you definitely came up with an interesting idea to boot - the scaled-up blocks having gravity disabled for a few moments after being shot could be amazing for some physics puzzles. If you leaned into that and made the shooting feel a bit more impactful (the blocks just kinda limply falling out the barrel felt a bit underwhelming), plus maybe a sprint option and some more jump height, you have the basis for a really cool physics puzzle platformer! Great job :)

Thanks! The blocks being janky was one of my biggest fights from a "I have no clue what I'm really doing" perspective and trying to make a square peg fit a round hole (building them out of the fps projectiles).
I had a few ideas to do with them with either dynamic sizing based on charging (to scale them up, to fit the theme better) of having them be more "sticky" to make using them to get around easier by being able to stack them, or countless other things that well...didn't scale well with my experience as a dev. :)
