I dig this game a lot. I've been playing it a bunch over the last few days trying to get beyond Year 6 - it's tough. It's a lot easier once you figure out some of the hidden combos, but still challenging. (I've only found a couple, I'm not sure if there's more.)
There's one strategy that I think is overall more sustainable long term, but requires a bit of luck getting a good deck for it.
I've noticed a couple of issues you might like to be aware of, though:
1) The discard gets reshuffled into the deck every turn. This can lead to you picking a card and then not drawing it for many, many turns purely because of bad luck. A better (more intuitive) system would be drawing through all of the deck, moving things to discard as you play them, and then shuffling the discard into the deck when you need to draw a new card and there's nothing in your deck. This means you're guaranteed to see all the cards in your deck within 2 deck rotations from when you've bought it.
2) There's a couple of hitbox issues. The status tracker in the top right appears to prevent you from placing tiles easily in the top right tile, and (more obviously) the top second-from-right tile. So you can click on space that's within both the box of the 2nd-right tile that doesn't appear to be covered by the status tracker and it won't do anything, but if you click in the bottom third or left third that's entirely outside of the tracker hit-box then you can still place tiles there. It's pretty annoying.
3) A similar sort of hitbox issue comes up when you have the cards raised to read details and you try and place tiles in the bottom row that aren't visually covered by the cards, but would be within a plain rectangular hitbox area of the hand overall.
Fairly minor issues, but would definitely make the game feel a lot better!
Cheers for making a really neat game.
