"I haven't played much of either Castlevania or Metroid but this didn't really feel similar to those at all"
It isn't, and maybe just my fault for that. The name is a placeholder because I had to name it XD. It has Classic in the title to distinguish it from the metroidvanias (aka backtrack, powerups etc); this has some dna of Castle1/3 as in: an action/arcade game where you move forward till the end and your powers reset on death.
The base of the gameplay is taken from an old (forgotten) classic I like.
I could rename it BaradukeVania for the next demo" I don't think there's a way to see your equipped subweapon, that would be good."
Completely agree, it's something I didn't add yet because till the last minute subs didn't even had a skin
" The strafing mechanic is pretty weird. "
As Rokas said, the problem is that I make you shoot with mouse and not w keyboard. You are not supposed to aim with your mouse because I don't want you to. This is/will be an arcade game for a gen4 pad, aka no right analog. You don't need to aim, you shoot where you are looking .
"Enemies can follow you through screens, I don't know if thats intended or not."
Yep is intended. Because since you can fly everywhere you could just pass through almost everything. Spawners and chasers make you actually play the level.
Thank you for your time dud.
