Hi! I'm new at b4a and developing a game; and I have an idea of making a 'word game'. So, my game is like tetris but letters will fall instead of blocks. The user will have to click sets of letters to form a valid word.
I just need ideas on how can I start making my game. Like libraries to be used and such. Anything would help.
Thank you :)
