Looking good Nesteris!
I found the movement to be a little fast, as it was hard to accurately jump on small platforms due to the left/right movement accelerating to speed almost instantly.
Having the morph ball assigned to a key instead of having to crouch twice is really nice though.
I'd sure like to see where you take this next. it looks like you have most of the Metroid basics down.
It's currently only that fast since it's still in the testing phase and I want to be moving around the level as quickly as possible to cut down on play-testing time.
Yeah I thought that was a nice little feature
I know that in Metroid Zero Mission and Fusion there's a lot of places early in the game where you have to change into Morph Ball mid-air and double crouching nearly instantly after jumping before hitting the ground can hurt your fingers, so I did that for gameplay comfort.
I think my next goal is to set up save slots like in Metroid and Zelda, if you want you can help me out by making a .capx and sending it.
Right now I'm thinking of using Dictionary keys to save values so the game knows how many energy, tanks and missiles to show on the save slot.
