Looks fantastic. Brilliant colors & landscapes. Zelda like play & puzzle schemes. Some camera issues.
You play throughout the game in two different characters, depending on what part of the story you're in. Most of the time you spend as Sphinx, the young warrior fighting the forces of evil to restore the powers of the Ancient Gods. Sphinx is the action and fighting portions of the game. The cursed Mummy, your second playable character, is actually Prince Tutankhamen, betrayed, tricked, and led into a trap. Mummy has no fighting skills and is relegated to only stealth and puzzle missions.
In addition to returning the crowns, restoring the god's powers, and saving the worlds in the Solar Disc System, you need to restore the life of Prince Tutankhamen, and challenge king Akenaten for his thrown and the love of Nefertiti.
The colors and landscapes look fantastic. There are no voices in the game, all your information and dialog must be read. There are only 3 game slots to save 3 different game profiles. There are save points scattered throughout the game, use them as you find them and often, because the game doesn't save between level changes or screen loads.
There are several side quests that aren't necessary to complete, but add to the game experience. At one point you'll be given "capture beetles". After defeating a monster, before you kill it, you have an option of releasing one of these beetles to absorb it's essence. You can later turn the captured monsters into the museum for a reward, or Hunter's Certificates (bronze, silver, gold, etc., they don't do anything for you, just for show). Try to capture all monsters you encounter (even friendly, harmless ones), because some creatures you only encounter once. It's not necessary to collect them all to complete the game, but at certain points, you must complete / collect a specific list before you can advance. In addition, you'll need to collect specific monsters to help you in your quest, e.g. exploding frogs and fire armadillos (to blow up or burn down blocked passage ways). Some of the side quests will result in you recovering a stolen jewel. If you return the jewel to the museum you can release one of the enslaved citizens, again not necessary to complete the game.
There are several mini-games (running, swimming, shooting, memory) throughout your quest. Although you don't nee to complete them all (each has 3 skill levels), playing them will help improve your skills for trials later in your journey.
There is the usual array of quest items and power-ups in any game like this that you acquire as you play (e.g. double jump, more powerful weapons, etc.). The main quest puzzles can be compared to early Zelda ones (finding and returning items, hitting switches in specific orders, meeting certain people, etc.)
There are camera issues with the game. Some times it switches at the worst time (for no apparent reason), and sometimes when you need it to switch or follow the character, it doesn't. Some of the quests and puzzles can be long and repetitive. Sometimes the capturing of the monsters is really difficult (the beetles and camera controls are the same, makes it difficult to fight multiple monsters and capture the ones you need).
Overall it's a fun game worth playing. Despite the 25 game-clock, because I died and restarted numerous levels, I probably put in about 40 hrs.
