A super polished, great looking and hyper well-made game!
The idea seems simple at first as you just switch between dodging and shooting. But then the game says "oh no", adds the extra zone, and reveals how it is so much more!
Your eyes start suddenly darting up and down the screen dodging and shooting and all while deciding whether to kill whatever is above of you for some health, or risk it to move down again. And it is the fact that enemies can also grab powerups that makes this such an interesting decision.
I also love how moving down-screen adds a huge load of dynamic difficulty, as you are closer to destroying you enemy but have far less time to react to their projectiles. At every turn the thing you need to do to progress causes another problem for you to try to survive.
Top marks from me!
