Not a bda idea, but poorly executed.
I don't mind too much that this is unoriginal, after all, I've enjoyed multiple games with the same game-rules employed.
However, the level design and presentation is a bit off.
1 - have instructions stating what needs to be done.
2 - have a little meter showing how far you are from the exit.
3 - have the ship explode
4 - have the levels start off easier and gradually rise to their maximum difficulty.
Actually, I'm not sure that making each game-type a single level is a good idea at all. After all, it's a real pain in the arse having to replay so much you've already done. INstead, if you had only 1 game-type, but had multiple levels, only having to restart the current level if you die, that would be better.
Or maybe you could have 2 game-types, but sorta have them rotate, like Axelay on the Snes.
In any case, good luck with future projects.
Stay funky,
