There's something that should probably be fixed: when players go near an edge, and sometimes when leaving a button, they get put into slide state and they can no longer jump. This makes you just fall off and die. This happens especially a lot in the final checkpoint of the game where there's a lot of buttons on small platforms and the knight slides off the button, continues off the edge, and just falls in the pit and eats you jump inputs, killing you. I ate the most deaths in that final zone because of this. The 2nd most in that section was the, uh boss' weapon being jank and hitting me while inside a cage (like right after I raised it, think bullets can just kinda slip in sometimes?).
Also, sometimes jumps are just slightly shorter than they should be on the base knight, might be because of the slight acceleration on movement startup (although I swear it happened on jumps when I was moving too), but on some jumps where you need your full jump to make it, it just kinda kills you and you dont make it. Some jumps he just like barely makes it and only if you dont air strafe and hold w down and jump at the last moment and keep holding w and he kinda pops up over the edge; then you do this baby jump and you just die when you cant spare even the smallest loss of height or distance.
But yeah glad to see you making something aside from atmospheric walking sims. Surprised by the amount of content in this game and there's even more secrets I haven't gotten unless I beat the harder difficulty.
