Love classic style shooters, but I feel like this one is still missing some things.
-All enemies look too alike, I understand that is because of aesthetic decisions, but have enemies with more variation on design, maybe shades of gray, and sound effects.
-needs more feedback when receiving damage, since there where times where I didn't realise I was taking hits.
-the level textures need a bit more variation
anyways, If you continue working on it, I'll check it out on next DD, I like doom clones.
