Really good game! I loved the gameplay and music (the music was reallyyy nice) The art is simple but good and fitting for this. I appreciate that getting hit only resets your position instead of making you start over, but having a way to lose (like getting hit a certain number of times) and restarting the boss fight would've been better in my opinion. As for the theme, I don't think it's the best representation of soccer. I mean, yeah I can see that you use balls, but they could be replaced with any projectile. It took me a while to beat the last boss but that's just me being bad lol. Overall, amazing game!! but it has room for improvement. Oh, and the illustrations are really good (the cover art and the in game ones)

Thank you for playing and the last minute vote 🙏 Glad you enjoyed it, if I were to expand or reiterate on the concept I'd probably redesign the stages to have threats, as well as making it possible to lose/force a restart with checkpoints, which would feel too awkward if it were possible with the current iteration.
The theme was definitely a bit of a stretch, the goal was to reach at least 3 stars for it without compromising on style, you're using your S-Ball to strike at the horizontal goals but they don't really give off a conventional soccer vibe I must admit
