The main challenge of this game is being quick and accurate while not having a crosshair. It sounds frustrating but is very well compensated by having very forgiving enemy hitboxes and short levels. However, the game unfortunetly becomes way too hard in worlds 4 and especially 5. Still, I did 100% the game, but only because of my stubbornness, not because it was enjoyable. I think getting all 3 stars in the first 3 worlds and just finishing the rest of the levels is the best way to experience this game. I think Neon white is much better, but this is still a fun little game if you want more of that kind of gameplay.
