Everything you said I agree, from the positive to the negative! Pretty much the most accurate comment about my game so far. Thanks for sharing your thoughts!
In the post jam, I plan to make it so jumping with robots above will push the whole stack and if it can't it shouldn't make the jumping sound.
Indeed, I wanted to add more levels with the automatic movement but I ran out of time. I also wanted more shooting mechanics.
Again, thanks for your comment!
