The color of B=b=betty's text makes it very hard to read and the inability to alter to full screen makes it even worse.

I won't be downloading the windows version due to the mini game with the 6mm target out of 20cm swing range. I have never really liked those hit the button at the right time mini games but this particular one is much worse than most. I have a brain injury and this game is the opposite of fun for me.
The space you have to target will not particularly change between the downloaded and the html versions, if you want to make it "fun" for everyone you could make an easy, medium and hard version with a larger target on the easy, a medium sized target on medium and a tiny target on hard. The other option would be a means to skip a mini game and still get the reward maybe with a note saying you advise against this for the sake of fun.
