Hi 40wattstudio,
Thank you so much for your review as it helps me a lot to update the game.
I have disabled library before publishing but I was unsuccesful to save. I want to put something else instead, but couldn't decide yet.
I used random.range code for collecting elements, so each game has a different collection amount but almost the same. I designed the game for players to be able to buy a new ship in almost every 3 levels.
Thank you for color coding suggestion, I will be updating it soon.
Unfortunately, first ship is a little slow. I kept it so to balance the last 4 ships, not to make them too strong.
I will do a quick update as I made a mistake in Prometheus and Corsair.
