VERY NICE!!!!
I like the graphics, and the game is very smooth, and the lander has a good feel gravity and thrust wise. well done!
Plays very well! Although the game is a bit hard, but that's just me...
(i'm currently stuck at some level)
Some ideas:
1) In the main screen, i need the mouse to select game, and also the mouse to select the level.
You should make it entirely so that you control the game with ONLY keys, without using mouse to select something
e.g. in the main screen, use up and down key to select (with enter)
(maybe it IS possible to NOT use the mouse, in that case, forgot what i said...)
2) Also, you use A, D and ENTER to control your lander. I find the keys a bit awkward.
Maybe an idea would be to make it possible to assign your own keys, and save those settings.
3) If the player switches to full screen, you should save the settings, so if next time you boot the game, it goes into full screen immediately (and vice versa for windowed mode)
How did you implement the thrusting of the lander?
Using GM physics, are just "normal" code?
Just wondering..
Great game!
