Really like the concept! I would make the first level a bit easier, or at least try to make it more introductory. I wasn't sure what to do at first. Then again, if you just call it a skill issue, I wouldn't argue :P
Thanks for playing! I am a fan of having little to no tutorials, so we'll see haha.
Edit: After playing some other games, I realized that my lack of a main menu gives zero time for the player to "strap in." That and maybe a level zero where the player just walks from point A to point B might help introduce the game better.
