ZapZak in Epsilon 9
The game opens with a slightly awkward, but effective slider puzzle, then gets better. The graphics are messy, but in an original way, and the sci-fi atmosphere is good. The robot blocking puzzle can kill you a bit too easily, but when you consider the game is rather short, it doesn't matter too much.
Nice presentation and cool title screen. This would get a four but the puzzles aren't that original.
Hot damn, an oldie that doesn't suck! ZapZak opens with either an impressive or horrifying title screen, depending on how you take it. Then you begin a short, seven board escape from a space penal colony.
I suppose I shouldn't spoil the puzzles, even though they're slider/sokoban stuff for the most part. The graphics are detailed (some boards having the maximum number of objects onscreen) and have a tendency to shift colour. References to Star Wars and pulp scifi and whatever give it a nice, corny vibe. There is only one part where you can lose health, so this isn't one of those games where you slowly take more and more damage until there's no possible way to complete it without cheating. It also keeps track of your score vs the best possible score, if you're into that.
Some objects that are supposed to die if surrounded don't seem too responsive, but otherwise, well done.
