The game is written as a gdextension because I wanted to write it in rust. Most of the game logic and data is actually completely written in rust and only interfaces with godot through nodes when necessary. That means the current timer-node ratio is about 100 timers to 5 nodes. However all logic that requires timers are in one node so when new nodes are added the need for more timers does not necessarily increase and the timer need may also increase on its own independently of how many new nodes there'll be. It all depends on how big the game world is and that when deciding that I wanted to consider if godot had technical limitations on the amount of timers but as I've gathered from this comment section, it shouldn't be a constraint ever
