Wow this is a really great submission for a game jam.
It give of some good stanley vibes.
For some feedback:
- the mechanic isn't that clear at the start. Which is a real shame as the game has much more to offer.
- for the platforming I'd suggest putting in a simple challenge to get started. The first one currently is maybe a bit much for the start.
You put the unreal engine to good use and had some great assets in the game.
