really ingenious  concept a lot of fun.

Yoyo Hero is a fun physics-based action game with a simple yet satisfying premise: control a yo-yo to destroy incoming bullets while protecting the smiley face attached. The graphics are excellent—I love being able to clearly see what's going on with lots of colour, and trails on bullets. The visual effects when you smash bullets or get hit are very satisfying too.

The controls are smooth and fun. The game has a good variety of bullet types, each with different speeds and durability, which keeps the gameplay engaging. Power-ups like bombs, shields, and triple yo-yos add depth.

The main drawbacks are that it lacks sound and has no story, so it can feel a bit barebones. That said, for a game jam submission, the game is solid and very addictive, especially once you start chaining hits and racking up points.

Overall, Yoyo Hero is enjoyable with satisfying physics and controls. Adding some sound effects or background music and a bit of narrative context could take it from great to truly memorable.
