This is a very inspirational game, I always have a habit of trying to make something two years ahead of my ability and the simplicity of this is incredible considering that so far it is the first game I've played form the submissions where I had to stop myself from playing instead of eventually losing interest.
I feel like there's a mystery element missing as there's not much reason given for why I should keep going (eg. an indicator of potential upgrades instead of having them just appear), but overall I adored the rain of items mechanic. It's genuinely addictive and reminds me of the kind of thing I would have probably paid full price for on an Amiga or ZX Spectrum when I was too young to have had any money.
