1. Could you make the aiming better? It's quite hard to shoot anywhere apart from centre.
2. Free kicks are extremely hard to score. Maybe add curl and/or make the shooting not exaggerate the amount of power you put in (also for normal play).
3. COULD YOU MAKE THE KEEPER LESS LIKE THE LIKES OF BANKS, YASHIN, OBLAK, COURTOIS AND GROBBELAAR COMBINED? He has supernatural ability with open play but 2% ability with penalties.
4. Cutouts for free kicks are quite simply unavoidable when taking free kicks. Whatever you do, be it full or almost no power, you always hit the cutouts. I'm baffled how you even scored the free kick that you put on this site.
5. Add more background detail e.g. fans, houses, trees, corner flags, cameramen etc.
Fix these problems and this may actively compete with the FIFA practice arena and at the same time be an extremely fun and recommendable game to play.
