Neat concept. Seems to lag on my computer which is odd cause I have a pretty decent computer, might be firefox or something (resetting seemed to make it run seminormally so probably just firefox). Main issue is just some lack of feedback, some of it just being questioning what the real solution is. It seems to be the point as it's a puzzle game but I did really end up feeling like I was solving it by unintended means.
Also some bugs:
if you jump and grab at the same time you can just repick up the corpse. It's fun if you could find a way to isolate it but it is too easy and invalidates a lot of the puzzles I found.
I was able to spike jump (though replicating this was hard)
sometimes a diagonal corpse wouldn't could as floor so I couldn't jump on it
on skewer slopes - chew the wall of horizontal skewer can hit me through the wall if I'm touching it while it is retracted (the hitbox seems to extend too far back on it)
This ended up happening with the vertical skewer on skewer slopes - extension as well
other notes:
I really wish I could just drop the corpse where I am or like right in front of me somehow. This would require testing I understand but getting the corspe exactly where I want is a bit of a gamble (jump, hold down and throw, try and move out the way is the only consistent way i could do it)
I feel like hitting r to restart should work even between lives (I had to wait for the next tofu to spawn in)
I felt a lot of the later levels (especially skewer spikes) didn't actually use the mechanic anymore. Only real advantage is making the next attempt a bit easier (or in some cases much harder)
