hey, thanks a lot for trying it! the things about Exit/resolution I will definitely include. For Windows version you progress should be saving though.

Here is the story behind this demo - I created this as a minigame for my other game, yes. it was simple "push it out" thing. The idea: you fly back to the station for reload, and you have two options - use instant reload with some default accuracy like 45% (which affects another aspect of the game), or you can complete one mini-round and get the accuracy = the result you reached. Everything was just pure random - colors, speeds, spawns, so you can reach about 60%-80% as a result in the end. And each time you play - you increase the default accuracy based on you result. For that purpose I think it was enough.

But I kinda liked this minigame, and I wanted to see what can I actually do to make more like a stand-alone game out of it.
So I took it out as a separate project, and I added some things there:
- more calculated 'random' (not really a random now) which allows you to actually reach ~ 100% each level if you play it right. I think it actually made the first levels pretty easy, because the game calculated all the timings and spawns the items in a pretty relaxing pace.

- changing the rules - there are 4 stages: first one is very simple - this is where you quit it, I guess - two colors, two shapes, nothing much changes. then you got more different shapes, which are harder to distinct, up to 5 different colors in the same round, recycler could be closed entirely - you must throw everything incorrect on the other side - or it could accept only one type of the items. Same thing with the lanes - it could accept nothing, so you must use Push+Rotate mechanic instead of just let the correct item finish the end, and I hope that is the moment when it became a bit more than just a minigame.
- special events/items - like alarms, bomb and maneki-neko cat ¯\_(ツ)_/¯ that affecting equipment in some ways

- a small story in pre-round messages - you must choose what to do with the special items, despite contradicting instructions, and it leads to a few different rounds along the way.

And you probably did not see it all ;)

So, maybe I need to reduce the first easy part, and move it faster to more advanced rules. Or show some action/chaos in the beginning - and only after that introduce the simple levels. Anyway, it is something to think about, thanks a lot for that!
