Anyone ever play this game? It's been in the mobile space for a while and recently came out on PC, developed by Nimble Bit aka the developer of Tiny Towers and Pocket Planes. It's a surprisingly fun Snake-ish game with Action RPG elements, where the "Action" boils down to your auto-attack on a bunch of roaming monsters and the "RPG" boils down to killing them for experience for your chosen hero, which may lead to your hero leveling up and gaining extra stat boosts.
The Cynical Brit has a video on the PC version:
Side note: while the mobile versions have microtransactions, the PC version does not. Instead, it costs $5 upfront with no additional payments required, and the game seems to have been rebalanced a bit to make up for it.
