Impressive work. Some suggestions. 1) Display the Price Multiplier in the main station view (i.e. what you see right after you dock). 2) Display ship stats in the main station view. Maybe a little card/column on the left with "Refuel" and "Repair" buttons on it. 3) Display cargo in the main station view. Maybe a little card/column on the right with "Sell" buttons. Maybe even a "Sell All" button and a "Store" toggle for each item so that you don't sell equipment you're trying to save. 3) Hover comparison for your equipment so you can easily see if a market item is an improvement.
The amount of recoil from firing missiles is a bit much. I didn't even bother trying to move most of the time since I'd just get tossed around the screen by recoil, explosions, and collision anyway and have no idea where I was due to all the clouds and smoke. The tininess of the screen compared to the speed of the enemies also made it largely pointless to move. Bigger play area and/or slower enemies. Better visibility. Less recoil.
The message I was getting from the game and the tips was pretty disturbing. It seemed to imply that love is about using as many people as possible for your own happiness without much concern for theirs.
In general I used the Bow. Used the Axe for a few specific areas and finished the boss with the X-bow. I didn't like that I had to dodge weapons to keep the one I wanted.
