Such a freakin' cute game, but still challenging and some decent level design! LOVE the TV screen effect, reminds me of Killer 7, and that's definitely a great thing!
This could use more polish though. The controls feel a little too loose. The lava comes out too fast in my opinion. It should kinda flow more as well, it kinda looks like red stuff. It doesn't animate/move like it's lava. Make it more like waves.
Other than that, I think you could have played with the "package" idea a little more. So have certain packages give you limited powers when carrying them. So, a blue one could freeze lava when you hold. Or another could help you jump higher.
That way, you could have more interesting levels, where players how to be careful which package they take back first and how, so they can complete the level.
Oh, and add some music!! XD
Overall, I quite enjoyed it! Great job, man! Hope to see you in more game jams! :D
