Planned updates

Just to keep you posted on some updates for The Ancient Art of Staying Alive:

- Credits and High Score table to be displayed more attractively

- One, or possibly two, extra game modes to appear as every 5th level in Challenge Mode. One thing the game desperately needs is some variety. I have two specific ideas I'm looking at implementing, not decided yet whether to go for one or both. Definitely I want to have some kind of Boss Level,

- Having somehow lost all my code relating to the Steam Scoreboards, I need to rewrite that. Probably add a few more achievements, though I might do that post-launch.

- I can do a native Linux version on Steam when it's launched there but the achievements / scoreboards won't work due to an issue with the AGS Steam plugin that I've not been able to resolve. Therefore I'm not certain whether it's worth doing a native Linux version on Steam since you can run it under Proton and the achievements etc will work fine. 

- Music... I'm very undecided on whether the game needs music or not. If you feel strongly either way, please comment on this update!!
