Nice concept, graphics in some points become a bit messy but still readable, maybe a few adjustments in contrast could help there. attack animation is maybe a bit slow, does not feel like a powerful sword swing. Overall a fun gaming experience, well done!

Had some bug / unexpected thing happening… in the room with 2 switches on the ceiling to open the doors with a big and a small box I was carrying the big one, picked the small one and it transformed into a big one…

I like the concept of this game.  A s other people said the controls feel a bit off/floaty/slow.  The pixel art is nice and varied.  At one point (on the level with a green box, a red box, and two switches above) I got stuck and had to re-start because somehow my mashing pickup/put-down turned  the green box into a red box lol.   I liked the animations btw, like the way the enemies turn into boxes for examples is very fun.

Clever platformer, the mechanic with enemies turning into blocks is great and I'd love to play more levels.  Also it wouldn't have hurt if the controls where slightly more polished =)

This is a really interesting platformer! I don't think I've ever seen the idea of enemies that turn into terrain when they die. I found it a little tough to control (I managed to get past level 4 using the trick you describe on the page), but it felt like I was wrestling with the slipperiness of the boxes now and then. 

For what it's worth, I think box-based puzzle platformers (where you move crates around) will inevitably have some slipperiness and awkwardness in the controls. This might restrict play too much, but I think snapping the boxes to the buttons when they're close might be a possible solution to some of the issues where a small nudge would displace a box from a button (and close the door).

I think I cheesed a few levels by abusing the fact that there's a delay between when a switch is released and when the door actually closes.

There are some great ideas here, and I like the small mix of combat with puzzle! The art was also perfect, the animation of the bots transforming into boxes was great. Good work!
