A very cute and nice puzzle game! Simple mechanic but can create a very complicated and challenging puzzle, definitely loved it! However I think there have some aspects that can be improved, for example, I stuck at level 2 for a long while because I don't realize that the pillar can be swapped. The keyboard key location also kinda awkward to control as "K","L" is not the usual key used in games and it have a long distance from the "R" and WASD key, maybe Q and F will be more comfortable.

Also, I got this bug when I swap and standing on the stuff that I swapped. 

I really liked the game idea!
I would love to see different items with varied mechanics, combining stuff would definitely add more flavour to the game.

The only negative thing is that it's not clear which items are interactable. I.e.: I didn't know I could move the flag, which is a big game-changer.

A cute little idea with a lot of potential for a full game, let down slightly by the fact that it's sometimes hard to read which objects can be swapped. I'd love to see you do more with this concept though!

This is a pretty cool game ! The controls feel very smooth and not floaty at all, the swapping effect has a certain crunchiness which I like. This can really become a very interesting thing ! Perhaps adding a shader of sorts to indicate what can be swapped (or even just give the object a slightly distinct look). Awesome job, can't wait to see more levels , but this is a great start, thank you for submitting it to my stream !

This is good. I would have liked more levels though and maybe more than just a few objects to swap with.
