The game is good for the jam! The music is a bit repetitive, the art looks good, but the gameplay is a bit of a mixed bag.
The jump arch and the general movement of the player is a bit restrictive while being a bit too floaty. The cooldown on the big box package doesn't really make sense, since it only makes you wait more which isn't ideal. The levels are a bit non-nonsensical, there are a lot of bits of the level which just doesn't serve a purpose in the level itself.
The restart is unnecessary in my opinion. Like, if I NEED to restart because the level design is basically a one way road with no ways to back track, I'll just not retry the level, because going back to the beginning for no reason other than the fact that I don't know the map is frustrating.
The interaction key is a bit unnecessary as well, the player only really goes to the truck if they want to finish the level. E is not used anywhere else, so having it automated and just finishing the level when you touch the truck would be better.
But yknow, for a game jam game with a very limited time to work on it, its fine. My only real issue with the game is the level design where I HAVE to restart if I go beyond a certain point.
