Thank you for that detailed feedback! I am happy to see that you appreciating the small details (especially that you noticed the spongebob reference :D)
I totally understand your critics on the gameplay however the spawns are actually random distributed within a rectangle. But still, some obstacles, a different shape map shape or a "smarter" random distribution of the spawns may be useful.
About the controls: I just played my own game again yesterday and came to exact the same conclusion!
So thanks again for your critics. It is very important for me to collect impressions of others to grow
