I loved the gameplay on this one. The game mechanics are novel and well thought out, and the game is really enjoyable as a whole. The game graphics are consistent and fit the jam very well, though there is no audio in this game.
There were two occasions where the game crashed while connecting markers, with the following error:
ERROR in action number 1 of Draw Event for object oOrb:
Unable to find instance for object index 100135 at gml_Object_oOrb_Draw_64
gml_Object_oOrb_Draw_64 (line -1)
Despite that, this is a really good entry.
