A well-polished platformer! The slow movement in the air gives a lot of control and creates a unique feel for the gameplay. Checkpoints are very generous, which makes the experience not frustrating at all (even if you're not good at platformers like me xD).
And the 2048 game at the end was definitely a surprise! I didn’t manage to reach what comes after, though.
Overall, it’s a good submission. Well done!
