Just realised that all those edgy games Newgrounds used to be known for would probably get banned off Steam today. I think Valve draws the line at killing celebrities and children, which I guess is understandable, but it's also cowardly.

Making the loading screen do less calculations on each frame so it doesn't trigger Android's bad behaviour thresholds if the app is unresponsive too long. Will also help on slower PCs too.

The rare cat sprite behaves differently depending on if it's a goal or not.
(whether it's your mascot, or just a wild rare cat)
The one in the HUD doesn't know what it is, so it has two faces.

Played through and finalised 83 levels in Matt's Hidden Cats this month. Ooof. The game currently has no thematic climax though, so I may need to make a few more levels to tie it together at the end.

Finished all of the achievements in Matt's Hidden Cats.
There's 90 in total, and while most of them can be collected through normal gameplay, there's a bunch you have to go out of your way to get, and they're quite tricky.

Trying out a new Windows file explorer called File Pilot, and it's way faster than the default one!
Makes ya wonder what would be possible if Microsoft gave a shit about their products.

Haven't signed into my Apple account in years.
Looks like everything is still working fine!

What if bald cats just have all the hair growing under their skin. Like if you cut them open they'd just be full of hair.

Here's your daily reminder to not time the stock market.
Simply buy a suitable asset allocation for your long-term plans, and stick to it for decades. Traders are degenerate gamblers.

Looks like the UK is gonna get rid of immigrants by making the UK an undesirable place to live. Taxes keep going up and public services are still bad. Poland is already overtaking the UK in terms of development, so Polish people are going home lol.
