The game's okay. The spriting is nice, as is the music. You've also done a pretty good job at setting the atmosphere with your map designs. You've definitely got a lot of potential for a solo dev.
I feel like the movements are a little stiff, and the sword's a bit sluggish; at least based on what I'm accustomed to in other Metroidvanias. I also can't figure out how to not get shot at by the first boss, ended up throwing in the towel after about 5 deaths. x_x (I had a max of 7 HP and the blood vial by the time I faced the boss, by the way.)
Maybe I'll pick it up again another day and suddenly overcome that obstacle. For now though, I leave you with my first impression.
Thanks for the feedback!
If you're talking about the Watcher Above (the green eyeball), it is technically optional. You can explore the underground caves without the ability it's defending, you're just going to have a very short line of sight. Pushing forward to the double jump would make avoiding its projectiles way easier. But if you don't have it, the best way is to watch for the moment it stops and quickly put some distance between you, so you have more room to see the projectiles coming and jump over them.
Also, if you went left instead of right at the very beginning to collect the item there, you can get the gun early (otherwise you need to wait for the double jump to get it). It may or may not help, depending on your playstyle: it's a ranged weapon, but it also consumes a lot of stamina and may leave you vulnerable.
Hope you stick with it! ;)
