Increasing the board size is a kind of small progression. If you go from a 9x9 board to a 25x25 board, your robots will make a lot of unnecessary moves at first, but once you have a lot of robots, you should be able to earn coins immediately, even on a 25x25 board again. Of course, increasing the board size is a loss compared to the immediate gains, and this is an area of game design that needs to be improved.
I'm actually using requestAnimationFrame() and delta to calculate the frame difference, and I've used the same algorithms in other games. I'm sorry I can't be of more help, but if I come up with a solution, I'll be sure to share it.
Unfortunately, JavaScript canvas games do not currently support vsync options. However, we have added an option to turn off number pop-ups in order to improve performance in v0.0.7. We hope this update will be helpful.
We have released an update to version 0.0.6 of the game, which includes a decrease in the progression cost multiplier from 100 to 33. Additionally, there are other upgrades available in v0.0.6. Thank you for playing and enjoying the game.
