Die Harder

This is a nice game, and actually has a lot of potential. I have a couple issues, though since this is a proof of concept you probably already know these.

The biggest problem (like with a lot of physics-based puzzle games) is how the physics itself works, causing some intended solutions not to work some of the time, while also allowing for potentially cheesed levels by making precise jumps or having boxes land at an angle to climb on them. An example of the former is getting crushed by pulling a large box off a ledge with you, with the box landing on either side of your corpse depending on the small adjustments you make during the fall. This adds real-time movements to determining a pretty important outcome in terms of how you progress through a level, which doesn't seem to be an intended feature. A solution to this could be hard-coded movements, where boxes pulled off ledges rotate 90 degrees before falling straight downwards and staying perfectly balanced on corpses before being pushed either to the left or right of it, where it then cannot be moved over the corpse again. Sorry if this sounds painful, maybe just non-rounded corpses and heavier boxes could fix this problem, but cases where boxes land on things smaller than them seem to lead to outcomes that feel like physics RNG.

( Not sure if this is a bug either, but your corpse not entirely filling spike pits can lead to you dying again, creating a second corpse at a slant, jutting out of the small gap. Maybe corpses being 2 tiles wide, filling whole pits, would stop this? )

Now for something more minor that I think could turn into a really interesting puzzle element: Checkpoints. As of now, if something is blocking a checkpoint you just awkwardly clip through it, I'm assuming to the nearest empty you-sized space. I think it would be far more interesting if a blocked checkpoint meant that it no longer worked, and dying led to a loss. On top of that, moveable and multiple checkpoints seem like a very natural addition to the set of level elements, needing you to think about where you want to respawn from. This would need more UI/art than just an arrow, but to me it sounds like a bug turned into new puzzles.

To end on a positive note I really appreciate how you can continue playing a level, even if you run out of lives. Each puzzle showed off a new and interesting idea, and I hope to see more challenging and fleshed out levels in a full release.
[Side note: I beat level 10 in only 2 deaths, hanging a corpse or two off a ledge to bridge gaps and long jumps seems to "break" it (though maybe this is an alternate solution?). This could be a pretty cool puzzle idea though ;) ]

for some reason #9 was the hardest for me but i understand how to do #10 instantly lmaooo loved this game :)

got stuck on lv8
super epic

Nice. Took me 45 min. Hardest part was figuring out certain mechanics.

That sokoban tag is misdirection. You can do a particular thing, that is not possible in sokoban. ;-)

This was fun!

I enjoyed all the puzzles, though sometimes the movement speed felt somewhat slow. It felt great in the earlier levels, but when the levels became larger and harder (more resets) the slowness started to become noticeable for me.

Very minor thing - it’d be great if you could hold down the push/pull button and walk into a crate to grab it. Sometimes I would press the button slightly too early and it wouldn’t grab because I wasn’t close enough yet. Maybe I’m just impatient 😅

I love how the 10th level felt like a combination of all the mechanics learned in earlier levels, but still required some brainpower to put them together in the right order, it was a nice way of ending the demo.

Good luck with the full version, this is a great concept!

Cool, I like this game! I beat it in half an hour. I think the difficulty level of all the levels is really good, except for the last one, which I found frustratingly hard, though I did eventually solve it. All of the other puzzles felt impossible at first until I played around and had the satisfying "aha!" moment, which was nice. I could imagine making them a tad easier, but I don't have a strong sense of whether that would be better or not. I do like that the game taught me its mechanics in puzzles instead of in text.

Speaking of text, I found the screen explaining the controls a bit cluttered and hard to read. I think there could be more margin in between each pairing of a keyboard icon with the text explaining what it does, so that it's visually clear what's grouped with what. But I also thought that presenting all the controls on one screen right at the start of the game just felt a little overwhelming — I remember thinking "Push/pull? What does that even mean?" It might work better to introduce each set of controls only as it's needed. Maybe they could be part of the background of the levels where they kick in. Then the player would have the chance to learn them one at a time.

I think the physics engine is just a little bit funky-feeling, but fine for the genre of game. There weren't any moments where I felt like I got away with something because of a glitch in the physics engine. I did feel, in the last level, that I was surprised that I couldn't drag my corpses out of the spike pit to get them onto the red button. That felt a little unfair, and I wondered if maybe it was the physics of the game just being finicky and I was supposed to be able to do it. I wonder if there's a way to communicate that that's not the intended solution to that puzzle. Maybe the spike pit could be deeper.
