Unfortunately this review will be quite brief, due to an unexpected issue I ran into. Alien Spidy is, in and of itself, a fairly solid physics puzzler. You swing from anchor point to anchor point, collecting little bits of energy, hopefully in a row, in an attempt to boost your score by reaching the end of the level. At 3 worlds and anywhere from 16 to 24 or so levels per, it doesn't seem exceptionally long, but the game is quite difficult, though not unreasonably so. The web swinging could use some work, which is a shame because it's basically the core of the game, but that isn't the issue here.
When returning to the game to make further progress, having already made it to the end of the 2nd world (no small feat, I can assure you), I started the game only to find the Continue option blanked out. My save file was gone, and according to the forums nobody knows where to, not even the developers. With such a game-breaking bug being so common, and with the developers seemingly planning to do nothing about it, this game gets a hard pass.
If it's ever fixed, it's a pretty challenging game that requires a lot of finesse, but when all of that effort can be dashed in an instant, something is wrong.
