I like it, when you destabilize the lander, lie down on the surface and shoot the enemies from side or from under while slightly turning left and right to aim :D
mercuburns: About the spinning - I don't think so, it just need some gentle turns. Control can be regained after a few seconds, approximate 2 seconds. Just try to put your lander into basic position (head up) for a second without spinning.
Tijamat: I used to switch walking/crouching on manual control. He can't hit you, when you crouch.
Liesmith: Use a fuse valve at lower (firing) connector and set it to high pressure. Upper connector can be permanently under pressure.
Great game with nice combined uncommon ideas. 5/5 for great fun.
an alien: with shield it is "3 bullets dead" and if you let the shield spell permanently in the slot, you can just quickly cast it after being hit. I died just once during the whole game. In second level use the shield immediately and quickly switch to flame and fly away.
Used slots: shield(permanently after getting 2nd slot), flame(permanently), house of lightning.
xxduduxx: If by last level you mean 5-5, it's about rotation of middle platform and jumping. You must jump back on that platform while it's in good angle.
