Thanks!!! We're glad you enjoyed our game! 😁
About the upgrades that was an important point for us. With an infinite runner game, the question of "why would the player come back" is important so, even with the short timeframe to make the game, we want to have something that can encourage the player to keep going!
For the player controller, it actually became more forgiving than we've initially expected it to be... but we left it this way because we thought it was more fun! 🤝
