Hey! Thank you for the review, coz what you've pointed out is actual problems. Now they are all fixed, game is much less confusing now.
Could you please play again? I'm asking that because you didn't see the main idea. + What you've played through was half of the tutorial. There's at least 5 times as much content as you've seen. (content, not time. I didn't mean game is half an hour long)
(I have no idea how you achived arrow key movement, theres WASD in code)
