As you probably already heard, awesome job on concept, artwork, animation, background too, level design, music and sound, UI, etc.
while i did experience a few (and very minor) bugs like not properly getting squished between 2 moving platforms and a frog with cannon abilities getting stuck in a corner that has a portal, the amount of freedom the player has to figure out puzzles is amazing
one thing I would've (personally, other people probably don't need this) like to have is some visual indicator of where the range of swapping is when not pressing x, so you don't need to unnecessarily click to check if you are in range of something else (maybe a highlight on the other object, or a less visible version of the circle range thing, idk; maybe make it togglable)
