Zero star puzzle.
Normal sudoku rules apply. Place the digits 1-4 once each in every row, column, and 2x2 box.
Thermometer: digits must strictly increase along each thermometer, starting from the bulb.
Kropki: digits separated by a black dot are in a 1:2 ratio (one digit is double the other).
Cells connected by a V sum to 5. Not all Vs are given.
Digits may not repeat along marked diagonals.
Solve in VariantDoku (iOS) or on SudokuPad.
Lösungscode: Enter the digits of row 4 (no spaces).

Agree with @supersim2000 that this is a zero-star as stated. That would actually be a helpful level for those just starting, like the zero level in rock climbing.

I don't understand the negative ratings.
It's a very easy puzzle, as stated in the description, and the thermometer, kropkis and diagonals complement each other.
