Fun game. It looks very polished and the idea is nice and fits the theme quite good. Movement controls felt good and the upgrades are unique and nice
Some feedback:
- The white text on the cyan/blue background of the upgrades is not very readable. (But I can manage)
- Is there a way in which you can see which upgrades you have, or which upgrades you take to the next iteration?
- It feels a bit strange that the ship pauses shooting bullets after some time while holding space.
Overall pretty nice game though, well done :^}
