Only Two buttons and movement? This is Super Mario Bros. if it had a sadistic difficulty.
Really enjoying it, even if the random generation sometimes screws you.
If you're trying to get upgrades, don't waste your time trying to get as far as you can. Just crash your plane immediately. You get 1 coin per run regardless.
Thanks for the feedback - when you make it past level 2, you should be able to see how beneficial the mouse aiming control method is when the levels become tighter and more complex. There are many games with WASD and arrows to control direction and rotation - perhaps you'd prefer one of those if you're using a laptop.
A few others are seeing the same, we'll be looking for ways to track this down in the near future. Thanks for the report!
