Test level button is higher than the campaign one so I thought you're supposed to play the test level first lol and was very confused. Aside from that, very fun expirience, would play more, the theme is used very creatively. Personally I think the purple slime thingies hurt the gameplay a lot, because they disrupt very fast pacing of the game with moments where you just stand still. Arguably the same can be said even about the death minigame, IMO the game would feel nicer if it just instantly restarted the level once you run out
