A game I made with couple of users of Godot Engine
1000 years after post-apocalyptic Earth, many form of lifes went extinct, including humans. An alien robot series, called Minilens, are cleaning up earth and collecting surviving flora. The game is won by destroying all Radioactive Barrels and collecting all flora. Aliens forgot that Earth has gravity, therefore Minilens can't jump.
