One of those games without a plot, or characters, or good graphics..
Where ya have to collect a bunch of nonsensical items or shapes to plug into a bunch of nonsensical holes or puzzles, which then opens up another nonsensical floor or level. Until you've eventually “solved” everything.
It’s fine, for the type of game that it is. Which is pretty dull tbh. Gotta review it to ‘get the walkthru,’ so yeah. Here ya go.
