Just defeated Kraid. A bit of a frustrating boss tbh with a lot of moves. A few deaths later I learned that positioning is key, as well as timing and some well placed charged shots at those pink orbs.
But yeah this is first time properly playing through a Metroid and having a lot of fun with it. Its like an old school game but with checkpoints. which is a godsend as the boss encounters can be a pita as with those dreaded EMMI's. Now back to playing!
