Thanks for playing! I'm glad you liked it. The speed does increase but is capped at a limit to make it managable. It could be a fun mechanic increasing the cap but making the gems wobble if pulled far away, "losing control" as you said.
The font is a custom one I made last summer! I'm happy you asked about it. I didn't want random placement for this since I think its fun to let the player come up with an optimal route.
