I genuinely enjoyed this game! It fits the theme exceptionally well and showcases a high level of polish. The game's originality and well-executed mechanics were impressive. I particularly loved the art style, with its stylized simplicity that was executed superbly. The music choice was also a great fit and added to the overall experience! :D
However, if I were to offer some constructive criticism, my main concern lies in the game's difficulty balance. On one hand, there are challenging aspects, such as the moving platforms, which could have been tweaked further for a smoother experience. Then on the other hand, due to the lack of a cooldown for spawning echo characters, it becomes quite easy to exploit the game mechanics. Once you acquire two echoes, it becomes a matter of cheesing the game rather than engaging in enjoyable and challenging gameplay. I strongly feel that some adjustments should be considered to address this issue. For example, implementing a cooldown between echo spawns or introducing a punishment system for excessive echo usage within a level. I understand that finding the right balance can be tricky, but based on the quality of this game alone, I have confidence that you can tackle this challenge!
Overall, I had a pretty good time playing this game. While it has some flaws and kinks that need to be addressed, it's a solid little short platformer, good job!
