I jumped into this bundle of games wearing the thickest of nostalgia goggles. Keeping that in mind, it's still quite a landmark in videogame history as one of the first games with seamless scrolling stages (which was new for PC's at the time). It's also a great game for aspiring game developers, the first two levels in ''Keen Must Die" are a classic example of interesting level design, teaching the player not to trust their environment or the way items are distributed through the stage.
However, the game does suffer of serious feedback issues, sluggish controls and a difficulity level that reaches the end of an asymptote.
Overall a must play, for those that like to learn more about ID (APOGEE)'s early titles and platforming from the early 90's.
