I believe I have an interesting problem on my hands. I have a project with a room speed set to 30 upon starting the game. When certain objects are destroyed in-game, the room speed should speed up by a few units. Upon the object destroy event, I have: Code: room_speed += 4 When testing the project, I witness several objects be destroyed over a duration of 10 to 20 minutes. I notice no speed changes in the game. I have the room speed drawn in-game, and when it reaches 100, it seems to play as fast as it was with the room speed of 30. When using the same code but changing the [+= 4] to a [+= 30], I notice the game speeds up drastically, and it seems to work fine. When it reaches 90, the game plays much faster than what the first attempt was when it was at 100. Of course, this is what I have noticed after about an hour of working with this. I'd really like to find a way to gradually speed up the game. Thoughts?
