Really fun concept for a game. I loved the little godot bullets that were being fired at me, and the way the character reacted whenever actions in game happened. The sound effects and music also worked very well, and it made me want to go back and play some classic arcade shooters!
I found it really difficult to make it between checkpoints though, as when I took it slow I ran out of time and going fast just overwhelmed me with the bullets. The plane was just a bit too slow compared to the bullets, and I think maybe having a clear point hitbox ala TouHou would work better with the bullet patterns from the enemies.
I think having more fuel would be useful, because you don't get a lot of slack in reaching each checkpoint as it is right now. or maybe a boost powerup that gives you extra speed for a while!
I think some animations for the bombs would have been good too, but with all the features in the game it's impressive how much you already did in a week!
I did also like that you gave powerups at the start to show what they did. Great way to teach the player how to play <3
