• The tutorial is pretty miserable so I just decided to skip it and figure everything out on my own
• Not really sure if the mouse wheel zoom feature is actually necessary for this type of game because typically you will just want to be zoomed out as much as possible for maximum stroid opportunities 
• The font is kind of hard to read but it didn't pose a threat to me (the only text-heavy part of the game was the tutorial and i skipped that)
• There should probably be a SELL ALL button in the shop OR the asteroid parts should just immediately be turned into cash. I can't think of a good reason as to why you would want to stock up on scrap as opposed to just converting it straight into money
• Even if you are constantly buying upgrades and keeping your energy up, it doesn't feel like you're progressing at all. I have no idea where the end of the game is or how close I am getting to it, so I will assume that there is no more content after what I am currently playing and will just leave the game and do something else

decent, keep working on it so I can give you more stars later :)
