Here the Splash-screen and other concepts I did for Engie, a prototype for the "2017 Double Fine's Amnesia Fortnight" gamejam event.
(from the website) "In ENGIE, you play as one of four engineers trying to protect your mining device from waves of golems. It's a co-op defense game for up to 4 players. A gamepad for each player is required."
