I really liked the core idea of controlling two connected balls and switching between them, especially using the connection to deal damage to enemies. The concept felt original and fun to play.
I also enjoyed the boss variety and the level design, and the enemies felt well balanced for each stage. The sound effects and music really added to the overall experience and made the game more engaging.
One small thing, at one point an “i” icon box appeared and I wasn’t sure what it meant at first. It might be helpful to show what it does more dynamically in-game. Other than that, I really enjoyed the experience. Great job!
