Wow, I was about to say that if one person made this, you've blown it out of the park. Thank God it was a team; otherwise, I'd definitely start feeling the imposter syndrome! I don't know if the team played Flash games back in the day, but this game captured them PERFECTLY. If you put this alongside other Flash games, I feel like it'd fit right in.
It shows a lot of effort and care went into this project, from the art and sound effects to the tweens and everything in between that I didn't mention. Great work on the game, and it was fun to play :)
