The constant switching of positions is not only an awesome mechanic, but a great way to create pacing. As you get closer to the enemies, their attacks get harder to dodge. It builds anticipation before you can get to the bottom row and unleash damage as fast as possible before you switch back! And there's also the fun scenario of being sandwiched between two enemies, so you have to dodge while also trying to get shots in on the guy on top.
My one complaint is that I wish the difficulty increased faster. It took quite a while before I started taking more damage than I was gaining in health.
This was a lot of fun and I think this has a lot of post-jam potential with new enemy types added. Great work!
