BarrelBots

Here is an excerpt of BarrelBots' description on Steam:

Barrelbots is a grid-based puzzle game where you play as small robots that can grab, stack, and carry barrels of nuclear waste.

Each handcrafted level offers a little "aha" - a new idea or clever interaction you didn’t notice at first, but once you do, you’ll wonder how you ever missed it. The rules are simple and intuitive, but they open into surprisingly deep possibilities - with a few unexpected twists... ;)

Accessibility notes:

• Gamepad will be fully supported.
• Unlimited undos and resets.
• No puzzles based on audio, timing, or colour.
• No time or move limits.
• It is not necessary to complete every single puzzle in order to progress.
