I can tell that a lot of love and care was put into the development of this game. Sadly though, there are a few kinks.
The gameplay is really interesting, actually. It helps immerse you in the worlds you visit. Looting space cars? Hamster poop? Just amazing, feels really adventurous. However it could've been leaned more into, with the player encouraged to explore more junk options. But I understand that the 10 days might've limited things a bit, so that one might be a bit subjective.
Additionally, the impossibility of carrying more stuff if your junk meter is full could've been communicated better, but maybe that's just me.
Finally, a sprint function would indeed be a great choice.
The graphics... oh man. I feel bad for having to criticise them, because they play a huge part in making things seem so adventurous. Things look really good overall, however... sometimes walls look like floors, floors look like walls, half-empty bowls of hamster food look empty... it has a massive impact on the gameplay. At first, while I was trying to make sense of things, I wandered down the starting neighbourhood only to later find that what I thought were walls was, in fact, a floor.
The audio and the tunes are solid.
There are some great ideas here, some of the graphics look great, and I can definitely see the passion. With some polish, things could be a bit better. As always though, good job everyone!
