I think its hilarious that you used vaccuums - it seems so random but also really fun.
The basic concept is simple and fun but i think it makes it hard to build interesting levels without more addons to the concept. Having to collect the dust and being able to bump into other vaccuums was a good addition, but to create really compelling levels it needed a bit more than that I think. Obviously it’s a Jam and time is really limited, so I fully understand why that’s not always possible.
I had lots of fun anyway! Some little things you did, like the grid on the ground that reacts to your hover, are also just a great attention to detail and understanding the players needs.
Well done!
