Neat concept, I wish the controls were the same phrase instead of constantly changing. That way I'd still have to type something random, but it's always the same for left up etc... and I could move around easily.
Especially with how sensitive the system is, if I messed up trying to type the word on the right I would trigger the word going down and would have to type out that word. And it seems you don't have to be close to the items to type the words, I beat the first level by accident trying to figure out the controls. Then when I got to the second level I realized there was an actual chest and key involved.
