It features three episodes that provide enjoyable experiences for both seasoned players and newcomers to classic puzzle platformers. The learning curve is well-balanced, so don’t expect to just grab gems and exit the levels effortlessly. Episode 2 is where the pace picks up, but it slows down again in Episode 3, and if you're looking for an updated fourth episode, you'll find that in the HD remaster. Overall, it's a classic OG Apogee platformer that I would describe as very challenging in places, reminiscent of what I call 90s hard, which may deter those who aren't accustomed to that level of difficulty. Also bring music with you because their is only sound effects.
