Simulator

• add SVG around the screen
• add buttons in SVG, especially for usage on a mobile phone
• scale the screen - need to first print on 160x120 canvas and then print this canvas scaled on the actual canvas - there's example in EV3
• gray out the simulator and display big play button over it, when it has no focus - otherwise it cannot get key events

APIs

• implement dx in scroll()
• add splash-screen and instruction functions
• some menu system?
• high score storage support (per-script in localStorage)
• add ellipse drawing (filled and empty)
• add empty rectangle drawing (using lines)
• think about frame handler order (see sprites.ts for a list)
• think if we want to support devices with very low memory (eg SAMD21 has 32k and one screen is 8k; we need double buffering, and also some other random memory which leaves around 1 screen worth of memory for the user)
• nice design for GAME OVER - probably should avoid text - localization
• nice design for splash
• better animations for sprites
• some rigid-body physics - make it easy for players to stop on platforms
• come up with a better color palette (we at least need gray)
• make palette swappable

Saving as PNG

• save screenshots during game play
• encode LZMA compressed program sources in the screenshot and have it download on "Download" button
• implement loading of such PNG files
