Codename Kids Next Door: Operation Startup game

Remember that old KND Flash game where you had to defend the treehouse? Yeah, this is the one where all the security systems crash and suddenly you're scrambling to hold off the Delightful Children, Father, Mr. Boss—basically every villain from the show at once. You start with just a few turrets, but things escalate fast when they start throwing everything at you. The art style nails the cartoon's vibe, and the chaos feels like an actual episode gone wrong.

First time I played, I totally underestimated how fast Father's robots swarm in from the left. Pro tip: prioritize upgrading your freeze rays early—slowing them down buys you time to recover when things get messy. Also, the sound effects are weirdly satisfying when you knock out an enemy, especially Mr. Wink and Mr. Fibb’s ridiculous defeat noises.

It’s short but surprisingly tough if you go for perfect clears. Still holds up as one of the better Cartoon Network tie-in games from that era.
