Exact copy of Blade of Innocence. Not just the idea, but the units, prices, tech tree, everything. In this one, there's a bug where the computer never upgrades tower range, so your rifles can dominate easily. Just play Blade of Innocence.
Fun game, nice idea for the puzzles. It would be nice to have a button that slows the game down. On a trackpad, it can be hard to click the flowers quickly enough on some levels. It's a puzzle game, so reaction time and accuracy of clicking shouldn't be important skills.
