Really fun! Just SO FUN!!! Lots of fun puzzles to do and even some secret rooms! Although it's got a few glitches like all other games, you can Hack into robots you encounter and even Kill them IMMEDIATELY after the hack! Watch out for crushers and incinerators, though. They are INSTANT kill! You dont want to walk under them Especially in hard mode because in hard, you only have ONE life! Plus, Some enemies might be even stronger than they were in easy! In the Final Hack, you have to navigate your way to the very master system of the ship, H.E.L (HEL). He's Very tough, Even though I have No Idea what H.E.L stands for. But If you fully Charge Everyone's Extremes, It will go Much better than without the extremes. Not going to ruin any more of the game, so Have Tons of fun playing it! Sorry for Wasting your time. If you actually read all this without, well, Skipping any of it, All I can say is, "Props to you.". Enjoy!
