I really like the look of King's Field, so maybe there was some unconcious influence there and I'm glad you liked it. But for the most part this was actually more inspired by Space Hulk: Vengeance of the Blood Angels. It just ended up looking more like Kings Field I guess lol The movement was intentionally made a bit slower, both because the player is underwater, and I thought it helped the horror-like feel.
Yeah the comabt is definitely lacking though, the only feedback that currently exists is a blood sprite particle effect, and a stabbing sound when a hit lands. I'll definitely be looking into improving that post-jam.
Thanks for playing, and the feedback!
