Very cute! Gameplay is fun and makes me wanna get a better score each time! The controls can get a little funky if you press multiple directions but other than that they were rock solid! Very good entry :)
1. My best is 165 2. You can keep holding the direction and it goes repeatedly. There is no input caching so it checks if you hold it down or if you just pressed it 3. Just wait when I add holes, falling blocks, walking enemies and so on ... eventually ...
