I am part way through this game, and I gotta say I love the vibes, and its super awesome so far!
I just finished the boss in the pyramid and I know the jam is quickly coming to a close, so I wanted to give you some feedback before that.
I was super worried the first time I died and it said "game over" but it turns out I was just teleported to the start of the dungeon with no real loss in any items gained. So that was a big relief. Maybe it would be better to say something different? or nothing at all? really not sure on that one.
I love the design of showing a boss move in a safer location with the mini-boss before having the player fight the boss.
When you jump across holes, you really need a lot of precision to land on a single block. I like to stand all the way in the floor square, and one pixel down means instant death. it makes it difficult to fight the final boss jumping from one platform to another, and a slight misjudge means falling to your doom.
Another thing that would be a big quality of life improvement is de-spawning the boss's projectiles if I fall in a hole, or making me immune to taking damage for a short time after taking damage. example: I didn't realize I could get the boomerang and make the boss fight super easy at first, so I wound up trying to jump around and corner it with my sword. The following thing happened a lot: I would try to dodge the bone (I think it has a fairly big (too big?) hit-box, so it's scary) and wind up falling into the floor. I would get picked up and set right in front of the bone, and the bone would hit me, and push me right back into the floor. Essentially taking 3 damage in a time span that I could do nothing about after the chain started, and feeling like I got one-shot by the boss.
A small thing is that whenever I fall into a hole while at one health, I would be put back on the floor again before blacking out. It would be nice to skip that step and loose my health first, do the check for health, and blackout to my last entrance instead of watching me get placed back on the floor only to die.
Maybe you're exhausted and tired, maybe these aren't easy things to fix, and all that is just fine These are some quality of life/ higher polish type changes. You already have a nice little gem here, so I am just hoping it gets as polished as possible. Also I may just not be that skilled at gaming, and I prefer an easier journey. I realize I wrote a wall here, but it's not because your game is rough, it's because its already great, and I am excited to see where it goes from here!
I can't wait to play the rest of it later!
