tl;dr 5/10; tower defense

Walk your avatar to a tree location to convert it to a tower. Avatar must approach the spot of dead creatures to collect coins and gems to fuel upgrades and more towers, while avoiding contact with enemies--otherwise, your own coin inventory is scattered to collect again. Avatar magnetically attracts coins or slingshots them away again. Avatar momentum is a bit slippery, but fine. Towers can be upgraded or salvaged for a discounted refund.

Complaints: 1. Coins and gems are often hidden in the shrubbery.
2. Abilities of each tower are described with 1 to 4 stars. How much is that? Who knows!!
3. What does each upgrade do? Who knows!! Why upgrade 1 tower over another or quadruple upgrade same tower?
4. Has the GUI feel of a notebook game, but it is done well enough for a PC, including key remapping.
5. Like many other games, you may not advance further in the game until you have acquired so many "rainbows" (perfect completions without losing any of the innocents who mull around the home base)

5/10 Sure. It delivers an alright tower defense experience
