Quantum Spectre by EdGE and GameGurus, is a puzzle game about keeping dangerous space boogers in check. Well, not literally, but basically. The concept is that you work aboard a station where "space spectres" (is that like GhostFacers?) are about to break free of their containment fields, which is bad for some reason, so you must place a series of mirrors and other reflective objects down on a field to direct a laser to power the containment field in a limited number of moves. If you complete a level in more than the amount of moves allowed, spectres will begin to escape and... do stuff? Everything you do, from dragging mirrors around to rotating them, costs you a move, so make sure you plan things out in advance, since the lack of an undo button means you have to restart the entire level if you make a mistake.
Eventually, you'll need to contend with making sure specific colours are routed to appropriate nodes, or making sure certain nodes are powered by multiple colours, or even blending lasers to get a specific colour of out them. Throw in some other objects like double-sided mirrors and the difficulty ramps up nicely... if somewhat unevenly, with what feels like a very long, gentle slope of levels players might find far too easy. It's designed to be an educational game, which is great, though some minor annoyances like the lack of colour-blind friendly options, the absent undo button, and how ludicrously tiny the light that indicates what colour laser a node is projecting is (which makes separating mixed colours a little more difficult than it needed to be whenever you encounter it ), means the game isn't quite as user-friendly as it possibly could be. For a lot of players, the premise is going to be too familiar, and the perhaps disproportionately flashy opening cutscene and spectre visuals won't be enough to really elevate it. Still, the levels are crafted with care, and the slow inclusion of new elements makes this a solid, beautifully presented little puzzle to cut your teeth on... and now you get to add "spectre containment specialist" to your resume to boot.
