The game looks very polished, but there are a lot of quality of life features missing. Like R for restart, movement also with WASD, saving progress, displaying the level in the top right and Z to revert by one action (though more difficult to add).
Though I do want to praise the great art, original concept and humour. I got stuck a couple levels after the graber guy was introduced. It was the level were you needed to get them all down into one long corridor at the bottom of the level.
