Here is my version of Glitch Garden: Forest Defender.
I stuck with the graphics of GlichTheGame, but there were actually some fairly appropriate ones for this game. One even included a fox! So I made it my game menu screen.
The Gameplay itself is fairly similar to what Rick proposes, my main creative change is that I think that gnomes should be small and therefore I swapped the role of the gnome (early defender) and the cactus (late game expensive and strong defender).
I’m also pleased with the music that was available at GlitchTheGame.
Enjoy, and please let me know what you think.
