Bug fixes

Fixed some issues with the Classic and Challenge mode that I thought were worth uploading :)
Classic: Tristan would re-spawn twice, at the same place, with the same direction, that was a bug
Challenge: Made spawning safer, the game would only spawn 249 enemies, making the mode impossible

I decided to leave the survival room in the game cuz why not, just know this is farrrr from the final product 💀

Before installing, remove the previous version of the game :)
