Gowydot Metal can get mathematical - math core
AnSchu Skull-Kill-Symbol is brighter now (see picture) [will be in the next version-update]
this needs more testing, as you maybe have played Crimsonland, when you have hundres of enemies on screen then the whole screen will be skulls 😃 I think a sprite of dead body + blood that is not accented would suffice, as you just need to give player the sound cue that the shot landed on the enemy and its killed, and let the player focus on other enemies that are more visibly distinguishable.
As for the UI, you need to also recheck the contrast on text, so that you dont get situations like:
Where its hard to read for people with slight color blindness.
Other than that, looks good
