Missed adding below instruction to the game -
1. Use A/D to move the striker and Mouse to drag and shoot the striker.
2. Press 'P' to pause and then 'Q' to go to main screen.
3. Level with red coins are boss levels, you need to first pocket queen then 1 coin to cover.
4. To buy powers you should have money more than the cost. Not exactly same.(Dumb coding mistake):(
