Played muted so I can't tell what the sound is like.
It's nice. Certainly seen better games in a ludum dare, like Cancelled Refuge.
Visuals - has its own charm, and it's surprising that you could get something looking so cartoony in 48 hours. However, I disliked the escape text, and prefer having one consistent font. My preference would be the "STOR" font you had, since it works well with the charm. The characters shown are goofy and make you remind yourself that you have to turn your brain off for a bit.
Gameplay - the endgame and the grind is a relatively bland experience. My experience is trying to work out the perfect math for stealable objects, and found that besides the presents and the gold, none of the items are worth getting. Even the lava lamp, which is a guaranteed 150 ... credits ... isn't worth getting because the gold takes a lot less weight and the presents especially take a lot less space. The combined synergistic effects of the presents and gold make them more profitable.
The maze itself isn't worth going into nor is it very interesting. It's relatively easy to remember its layout given a few moments of time. It might have more consistency in providing the above items but I find plenty in the Mansion to not overwhelm any player that upgraded their carrying abilities.
Keep it up though!
