Need to add something that shows you're hitting the enemy

Howdy all, I randomly came across this title, and I'm just curious if anyone's given it a go on the SD. Also, "positive" with 100% positive feedback? Seems kinda overwhelmingly positive to me.

The game is fun but the map is completely overwhelming. There are several areas that require keys or later powerups to get through, but no way to distinguish them on the map. One of the big problems is the permanent fog that makes it very difficult to remember rooms. Little icons for shops, locked gates, crates, etc would be amazing....
