Overall I enjoyed it. You did an amazing job with the pixel art and overall atmosphere. The story was also really nice and I like how cryptic the whole game feels.
The idea of timed doors is a nice twist on the metroid door cliche. Really creative. The HUD also reminds me of the older metroid titles as well.
I enjoyed the little optional power ups. Some of them were fairly challenging to get.
But I want to complain about the movement a bit. I know it's probably by design but it really doesn't feel that nice. The jump is really floaty but also way too short somehow. And in general the speed of the character makes the game feel very sluggish.
I think it's also an odd choice to have the dash unlocked from the start but only on the ground. I would probably have enjoyed it more if you just game me air and ground dash at the same time when you get the air dash.
Only one rating btw ? This game deserves far more attention. Thanks for making it.
