I thought it was very fun (and it DID feel like metroid the whole way through). :D Also, just a side note- it didn't load up on firefox for me, but it worked just fine on chrome...
Fun. My only problem was actually the part after the ending. After I killed the boss, the game made me go back a second time to the same level, where the boss was nowhere to be found and the enemies came and came until I was down to negative 377 damage...Then I think that they just ran out XD Other than that, great game.
As soon as the last comment popped up (the one after "The End", I got a wave of goosebumps that ran up and down my body... RIP Katheryn and good luck Jack.
