This game has the potential to be an interesting puzzler, it just needs a lot more polish and it'd be pretty great! My main complaint with the gameplay is that the controls were a bit too awkward to work with. I needed to constantly think about which tools were where and what I needed to do with them in order to get them to do what I wanted them to. If this game is expanded further I also think it would be a good idea to not introduce all of your tools so quickly, as I think that could easily overwhelm players with too many variables that they need to think about. Introducing the tools one at a time and slowly showing what they're good at in separate levels would go a long way in teaching the player how to navigate the world!
Other than that, I would've loved to see more levels to see what else you could've done with this idea or where you would have taken it. However, I guess you ran out of time.
The presentation was pretty good though, and I do like the idea of a puzzle game where you play god to reach a desired outcome! Good work and keep making games!
