I was searching through the Greenlight section for games and this game stuck out to me, decided to buy it and give it a chance and I have no regret on it at all. The game is very good in my opinion and honestly, made me think I was playing a type of Metroid game, has quite a lot of similarities with Metroid, achievements/challenges for beating the game in a certain time with having all items collected, items/health to be found scattered in obvious and secret areas, bosses that are needed to beat to obtain items to open the next path, even a different suit that is purple and makes you stronger and take less damage, just like the Gravity Suit. When I had gone a few rooms to the right, I instanly thought of a similarity to Brinstar on Metroid Zero Mission, Dark King's Lair reminded me of the depths of Norfair from Zero Mission and there is even one dungeon further on in the game that will reminded you of Metroid games and Tourain (you'll know when you get there.) But enough about comparing this to Metroid, this game is hard at times as some of the bosses can be tricky the first time you fight them and you will need some quick reflixes on certain areas of the game. Overall it's not bad at all, didn't think it would be as enjoyable as it is. Controls weren't hard to get used to, lots of items to collect, soundtrack was done pretty good, nice boss battles that can be difficult or easy depending on how you go about the game and what items you have, another character to play as once you beat the game with her own story as well. Achievements in this game are quite the challenge on some of them, but that's what makes the game better, so if you're the type of person who likes challenges or going for harder achievements like me, then this will be perfect for you. I will say though, this game is going to bring back the older days with me, going back to speed runs which I haven't done in a long time. Amazing game, very enjoyable and very satisfied with my purchase.
