Yes this is my 2nd Jam. But hopefully not the last.
The variation is a problem and if I did have more time then I would have added more enemies in it to spice it up a bit.
After the jam was finish then I got an idea for making it harder (I did not think about it before the deadline). I could use the score as a factor of the speed. So the more points you have the faster it moves. Do you think that would have helped on the difficulties?
