An alright game with flawed design
This is a cool idea with some obvious nostalgic value, perhaps.
This is a simple game with some addictive aspects. However, I think the mouse drag gameplay is a bit annoying and boring. The core mechanic relies on a mouse that acts well/perfectly, which is not true. So even when you are doing really well, you could lose because of a freak skip.
Also, the random nature of the game (perhaps the things, i.e. fish and eggs, are programed ahead of time and it's memorization only) is not conducive to long playthroughs.
All-in-all, this game isn't bad, but in the end it's bland gameply covered by iconic tunes. I think you'd be better suited copying Elite Beat Agents or similar style gameplay where hit detection and memorization is the key. The 'dodge' mechanic is kind of cool, but I don't believe well executed.
Keep at it!
