I think I played this one on day one or two of the jam and it's nice to see it develop!
Really strong presentation (both looks & sound), really nice simple gameplay of outpacing the drill. I like that you gain lives after 50 gems, though tbh I'm not sure the game would be worse without lives.
I sucked at the game, but through memorisation and repetition I felt myself improving, like a simpler version of Meatboy. It was nice seeing myself improve in real-time.
The jump's a liiiiittle too tight for me, but that might just be me. Also, I haven't fully tested it out, but I think walking down-slope and jumping might not work all the time.
Good job! A game I could see myself coming back to.
