When the Itch.io download screen said, "name your price" for the download I thought "That's a bit cheeky!" But, now having played it, I'm thinking, hey this could actually be a game I would pay for.
It's super polished, a great concept and well executed. A tower defence game on rails is a novel twist as far as I know. Kudos for thinking of it!
Graphics are really well put together and the levels are well paced with increasing difficulty.
Despite the instructions I was still initially confused, but picked it up quickly enough.
Really solid game entry
