Megamur

Starts out with pleasantly tight ammo and health balance but mellows out pretty soon after. Action is good enough to keep you alert most of the time with a few close calls sprinkled here and there, but only really cranks up the difficulty at the end. New color palette with heavier blue emphasis adds a nice layer of gloom to everything, though sometimes makes visuals overly dark. A fairly fun action romp but doesn't excel enough at anything to make it noteworthy. 3/5

The way the levels are interconnected is pretty cool, where you can see parts of the other maps from windows and such, and can even revisit part of levels you completed. The massive scale and complexity (for the time) is something to behold, too, and limited supplies make combat tough. However, it starts confusing and gets worse, culminating in the awful Map03, which is a headache-inducing teleporter maze/invisible bridge combo. Artifact has aged poorly. 2/5
