Hello! Welcome to Feedback Quest 5! It's nice to meet you! My name's Hythrain. I'm part of the FQ team and a hobbystreamer. I'm writing this review live after having played your game.
I want to start quickly with my love for this type of game. I'm a big fan of Metroid and Castlevania, so it should go without saying that when I saw this mention being a Metvania that I was excited. The controls were pretty good and I really made my way around.
The three biggest issues I had were that there were too many instant death traps, having a hard time getting the spear into small gaps when doing a small jump, and the use of the middle click attack. I'm not a big fan of a game that makes use of it, since mine in particular isn't easy to click (I don't use a gaming mouse). I noticed Left Shift worked for it as well, yet this was awkward to use while moving. I'm not 100% certain what the best solution would be, but I don't think it's this. I also think there should be a delay from when you throw the spear to when you can call it back. It's a little too easy to be spamming it and you keep summoning back to you and getting no where.
Beyond this, I like the world, I think the Naruto headbands are cute and I'd like more plz.
