Hello,,, I already know how the library works,..,. sprites, timers, and so on ... just let me do it for you... You will have a unique solution for this. The game is not too short like can be done in 1 day ... because level 4 and level 5 are quite tricky. I can do it in linux...but I know, it is compatible with mac os. I should be the best option for you. I have more than 20 years working in c and c++ ...
