Thanks you for giving feedback!
I've already updated the tutorial so you can no longer die on the tutorial as I've noticed it leads to frustration and skipping of the tutorial which defeats the purpose of it. So this is coming in next update today or tomorrow.
I'm a bit confused what you mean by there is no mini map, the tutorial does show you the radar (minimap) after you learn the weapons and the carrier shows up in the bottom right, maybe you didn't notice it? I'll make it so it gets highlighted and the text box is nearby it too.
Controls are a bit difficult to pick up at first that's expected if you haven't played Luftrausers basically but maybe getting into the sea is adding overwhelming and unnecessary difficulty. I might prevent that until you have managed to get through all waypoints.
I need to find ways to ease people into the controls. The thing is it's a question of feeling / getting used to it so I'm not sure how I can make this easier. Maybe I need like a GIF that really shows the concept and how the controls map to the aircraft / the screen.
I will do another iteration on the tutorial, especially to improve ease of understanding for new players who haven't played Luftrausers, I really want people not to give up because it gets a bit of time to get used to it. Designing a good tutorial that can really teach anyone is so hard (this will be 4th iteration on it xD)
And about your other feedback about health, next update also has a completely reworked HUD with exact display of health + hit overlay + regen overlay + critical integrity alarm state.
I've also added a last chance effect where if a projectile is about to kill you it triggers a slowmo + slight zoom in + black/white with only colored projectiles and aircrafts so that you can have a little chance to escape or you will be able to see very well how and why you died, it really feels amazing, especially in situations where you manage to escape like 2-3 times in a row.
Thanks for your feedback it is very helpful and gives me many things to consider to improve the game further. I think after next update the game will be in a very good state, very close to be ready for public Steam playtest!
