Apart from the Goat which caused some issues, this is a well-balanced game. Music and background ambient noise works well, sound effects are nicely balanced and the artwork screams VGA (in a good way)!

As mentioned on Discord, some feedback:

• Lines are sometimes not drawn properly (sometimes with holes, sometimes completely invisible) -- scaling issue?
• Line drawing mode is still active after activating the "help book" item
• The "piracy warning" is confusing, maybe go with "this is the shareware version" pretending :)
• Inputs (keyboard, mouse) could use some convenience shortcuts (undo, do something with right mouse button) or make it possible to control fully with the mouse (e.g. have the mode toggle [SPACE] as clickable tools on the table, exit draw mode with right mouse button)
• The mouse cursor thing (bottom right icon(?) attached to the mouse cursor) doesn't seem to have any function apart from a decorative one, so maybe drop it and make the cursor more prominent

All in all, I enjoyed my playthrough :) Just needs more levels/content (for the registered shareware version? ;) and (for bonus points) a native DOS port.
