Big fan of your GB and retro games, this one is definitely another jam winner in the making.
The art style, effects and gameplay all give off lots of Gameboy soul, so top marks on that for sure. The simple pixel art is really charming. I am definitely taking down notes from this one for my future GBJAM entries: that toning down on effects and sprite detail doesn’t necessarily mean sacrificing Graphics.
I love the interpretation of Old Gold as well, and only the second “oil” themed game I’ve played in the jam so far.
I would have loved more levels and more difficulty, but this is just a good enough scope for a game made in 10 days.
Congrats on this one and I hope to see you again in future jams!
