Downloaded fine now. Adding to what Lenn suggested ...
* A shadow to make it easier to judge when the craft is about to land.
* Slow down the control of the ship. You can still make it exlode by requiring the player to perform a more accurately controlled landing.
* Mark out a landing zone to aim for.
* A nice big explosive sound effect.
More importantly though, the camera needs attention.
Maybe keep it in a fixed position just above ground level?
Oh, and have a play with Jupiter Lander (Commodore 64).
It has a nice 'pick up an play' feel to it. Plus, a delicate control system for the craft.
I can send you the Cart image which can be used with the excellent C64
Vice emulator.
