Schematic

[b]edit:[/b] every issue got fixed (undo, back to menu, windowed mode), so flipped the review to positive. [b]schematic[/b] is all about turning on lights, much like [url=https://steamcommunity.com/id/dohi64/recommended/1348160]turn on the light[/url]. in this case, both black and gray energy has to reach each lamp, at which point they'll excuse themselves from the circuit. that's the general idea, though there are a few other mechanics, like fuses that disappear if they don't get energy from either end, but their removal is not a win condition. in fact, their presence is often crucial for solving a level. [b]40 levels[/b] unlocked one by one, and about a third of them also offer a challenge. turn on the lamp in a certain way or within a certain number of moves, etc. solving them however you can still unlocks the next level. there are also a few 'bosses', but they're just different takes on the mechanics, nothing to worry about. rotation only works in one direction and short-circuiting is possible if black and gray energies run into each other, but [b]while a single misclick fails the level, unlimited undo is available[/b], got patched in shortly after release. the presentation is really pleasant, both the minimalist graphics and the audio, and there are separate volume settings and some languages, plus windowed mode got patched in quickly with a resizable window, along with a back to menu icon on levels instead of having to press esc in an otherwise mouse-only game. it's done well overall, the price isn't bad either, and with all the fixes it's now recommendable if you're looking for circuitry-based puzzlers.
