Nice work for a first. My top score was about 1580 after about 3 or 4 shots. Nice game. Would have been a great came with better graphics or maybe even just a different theme.
You dont need good graphics for it to be a good game. Maybe if you gave it a pen and paper theme it'd be cool. Pretty simple and little graphics work needed. You just need a theme.
Keep up the good work, Be great to see more. I think you should work on improving this game further.
