As others have said it was too hard to figure out what commands were expected at first. But when the death screens specifically hint at what commands to use it was very fun. The loop of trying the first thing that comes to mind > failing > getting a hint for the next step > trying the next thing is actually very fun; without explicitly needing a lexicon of commands. So I think it just needs a little tuning. Otherwise the art style is so unique and charming. I've never heard of lvllvl before so I will be checking it out.
Really neat!
