Like most of the games submitted at this jam, its a nice and simple little game but in my opinion, the drill's too fast. I think slowing down the pace of the game will surely help new players to grasp what exactly is going on. I also believe some sound effects and music will lighten up the feel of the game but I understand that 3 hours isn't that much time. Still, good job for still making and submitting your first submitted game jam game and good luck on your game dev journey! :)
