v0.4.0 - Completed most cards and content

This version is one step closer to the finished game. It’s missing only a few more assets, and some more polish on the menu-ing.

• All 15 cards now have completed assets.
• 5 different AI opponents are programmed, the last one is still pending implementation.
• There’s currently 2 different backgrounds, more are expected to be added.
• 15 different stages to complete, each with increasing difficulty.
• The Itch.io page has been re-designed, to be more fun to look at.
• The steam version of this game now has achievements.
• Implemented “Optional effects”, which allow the user to discard another card, to increase the effect of their current card.
• The first few levels now show less cards, making it easier for the user to get used to the game, before introducing cards with more complex effects.
• Despite all the new features, the new binaries for Linux and Windows are almost half the size of the previous version, thanks to some optimisations (from ~40MB to ~20MB).
