This was a brilliant take on the theme. The concept of the game is very cool and I could definitely see this being a longer game with multiple aliens/environments to puzzle over.
My main gameplay frustration was that I repeatedly got Ding Dings that were impossible to place. Maybe I just misunderstood, but I got like 5-6 of them that wanted to be near the table and near the door, so it wasn't possible to place. Not sure if this was intentional but left me with a feeling of "ah I can't manage this, better just shove them far from everything"
But overall this was honestly a great idea. With some visual polish I could see this being a really fun and expandable game! I had fun playing it
