Watching the process of this game being created was awesome (especially an interesting challenge in attempting to provide programming assistance via twitch chat), so finally playing this was pretty neat.
The voiceover was nice and chill and pretty funny, the physics jank was fun, I actually didn't know about the red button as I think the part of the stream where that was worked on.
I think some neat little technical things that could be worked on in the future would be small details like adding an animation to the red button when pressed, maybe adding sound effects to rigidbodies when they collide against something with enough force. Of course there some other things that could be added, like the jump that I saw you add at the end of Saturdays stream. And I noticed the end screen doesn't seem to make the cursor reappear, so you can't click the buttons that appear.
But as far as the goal of learning and reaching a minimum viable product, I think this excelled in that department. I look forward what the company comes up with next!
