Game Maker 5.2 game example with an automatic game save after each level is finished.
Balloon_Catcher. This is a game in progress. You fly around as a bird catching balloons. The game was originally started as an example of how to make an automatic game save using a save file name chosen by the user. So a few simple levels were made for that purpose. Then I continued working on it making new levels. So far there are 6 levels. In level 5 and 6 there are also mini views so you can see how that can be done (for that you can also check my Mini View example).
Works with GM 5.2 and 5.3, with GM 6 there is quite a few changes needed: view variables, font settings, maybe more, but the automatic save game method works fine in GM 6.
