Definitely a great, fun game! The puzzles were definitely amazing, with the ability to only hold one key at a time helping that - with only two mechanics and seven levels you came to a great level of depth. Sometimes, even if you knew what to do, you would fail, which was sometimes an annoyance but was more often a great challenge in execution. Animations would have been nice, especially just the character raising and lowering their arms when they pick up a key, but that's a minor gripe. Great job!
It'd be awesome if you rated our game, Donut Wholes, as well!
