My game simple collect fuel as a ton of spikes in a space cave are falling on you be careful as they can explode your ship also if you do not make it to the blue landing pad when the cube is not there it will explode your ship once you get to the landing pad you will procede to the next level but be careful things get harder as you go on.
Disable colliders using C
Load next level using L
Well done on completing your game, I just have a go and it is fun trying to avoid the spikes
Well done!
I had to skip the first level, that’s hard to the point of sheer evilness, ok, I’m exaggerating, but that grey block is quite annoying.
Good game overall, the spikes mechanic was quite fun.
Great spikes mechanics! Reminded me of old 8-bit Prince of Persia falling floor-plates. Nice difficulty level, for my taste 
Two things I’d change.
1: make the first level change to a later level. For a starter level this is way to difficult ( at least for me 
)
2: make your fuel into a Trigger (if it is a pickup), if it is supposed to stop the rocket then you can keep it
Otherwise, neat game
