Seems like a bit too ambitious scoping and didn't quite get to finish and polish enough.
The "main mechanic" wasn't really used at all. And now after reading the description, it's not too metroidvania either... 😅
The art was the best part. Nice looking pixel art with some good animations. There was some weird flickering lines in the middle of the screen at times (sprite tearing maybe). Not really a deal breaker but annoying looking nonetheless. The audio side was quite bland. The sound effects really lacked some punch and the music didn't fit too well either.
The controls weren't too great. Everything was just too clunky. The jumping was super awkward, the initial horizontal momentum was way too much and you didn't have enough control afterwards. So almost like that completely locked jump of NES Castlevanias but without the game designed around that.
Didn't really get the combat before I really had to on the final boss. I got kinda frustrated on that long stretch of enemies because I couldn't really fight an enemy reliably without getting hit. So I just ran past everything. But yeah, obviously I had to learn the combat on the boss and then it did click with me. After beating the boss I did a quick second run killing everything and reached the boss without a single death. 😎
The second swing of the attack was completely pointless. You pretty much always had to dash cancel out of it or you'd get hit. The enemy telegraphs were not enough for my old man reflexes at least. I couldn't really rely on them so I had to just swing, dash cancel past the enemy and repeat until victorious. And the same tactic on the boss too. The boss was also a bit too relentless in my opinion, some downtime on the attacks would make it more organic. And obviously some different attacks would help too but seems like you were struggling with the scope even now.
Happened to me several times that I dash cancelled at a wrong time (I think at least that it is timing related, didn't seem to happen if dashing right after the first swing connected) and was completely locked out of attacking for a huge delay. Like over ten seconds. 😡
Anyways, good job on making something completely playable even though it seems like it's not quite what you were aiming for originally. Scoping correctly is always difficult but gets easier with more experience and knowing what you're capable of. 👍
