Post Game Jam Update

This is just a bug fix and feedback update for Tower Punch. I have decided to take the feedback into consideration and tweak some issues that I had from feedback during the Game Dev Tv 2023 spring game jam. Fixes include changing level three to be much easier, increasing the number of lives to 10 and removing a bug that allows the player to constantly wall jump if they spam it even if they are not on a wall.  I do plan to leave the original version up as well for users to experience both versions. I also added thumbnails to the page, which I forgot to do during the jam.
