Really interesting mechanics, and the online leaderboard gives a genuine reason to push for a high score (even if the top ranks are way too high for my mediocre skills)!
A small downside: the hitboxes can be a bit frustrating at times, as arrows sometimes go right through a balloon without registering.
A few ideas to polish it even further:
- Rebalance the large balloons, as they don't feel super rewarding given how few points they grant.
- Allow firing multiple arrows at once to guarantee a hit.
- Add a mechanic where you lose arrows if a balloon manages to reach the ceiling.
Overall, really cool project
