Good idea! But this game is too difficult for me.
(1) Moving is difficult. No problem for me, and I enjoyed it.
(2) Aiming is difficult. The bullets don't follow the cursor, so I have to stand in the same position for a long time to calibrate the gun.
(3) As a result, I can't dodge bullets in this bullet hell game. All I did was stand in the same position, adjust my gun position, and try to eliminate the enemy's bullets with my bullets. I'm not sure if this is your intended game design.
