Super interesting movement system! Feels a little bit like controlling the ship in Outer Wilds, but in 2D. It does make the precision needed to dodge bulets very difficult, but the shield is forgiving enough that you don't need to dodge too much. I really liked the gradual introduction of gameplay mechanics, though I would have liked to see a little more variety in the level design. Also, I am not sure if it is just me, but I did not get any sound or music, was that missing or just on my end? Overall, great work, I would be really interested in playing more!
