Things I like:
- Very well polished visually, sticks to the style
- Good and fitting music
- A huge variety of upgrades
- Unique idea and gameplay
Things that need improvement in my opinion:
- The sprites' edges are very sharp, so the text is kind of hard to read
- Some upgrades feel pretty useless, like better control which improves the said control just by a little, so maybe it would be good to balance the upgrades out
- Not a very strong connection to the theme
