Really cute little game. I enjoyed it a lot. Also - it was really fun to come across a PICO-8 game among the entries! Great work.
Aw, glad you liked it!
And yeah I'm actually kinda surprised how few PICO-8 submissions there seem to have been for this. Based on the recent games with the PICO-8 tag it looks like there were 4 others submitted to the GMTK Jam, but I haven't seen any of them on the PICO-8 forums (despite there usually being a flood of them for things like Ludum Dare jams).
