Also, I think the amount of coins people get per minute is low as many people like to progress fast. If you are increasing the amount of coins people get, increase the price for each action.
Other than that, I think this is a very cool concept for a Roblox game.
Reversing controls: players’ movement controls are reversed, making it difficult for them to navigate through the obstacle course : Manipulate input that controls players’ movement so they move in the opposite directions.
Blindfold: players’ vision is obscured, making it harder for them to see the obstacle course and any hazards : Apply transparent overlay on top of player’s screen to obscure vision.
Slowing down: players’ movement speed is reduced, making it harder for them to complete the obstacle course in time : Reduce player’s movement speed or apply force in the opposite direction of where they are going
Mirror image: players’ view of the obstacle course is flipped horizontally, making it disorienting for them to navigate : Manipulate the camera’s transform to flip the image horizontally.
Ghost mode: players become intangible, making it hard for them to interact with physical obstacles like jumping over walls or moving through tunnels : Make the player’s character intangible or give them the ability to walk through walls
Inverting gravity: players’ gravity is inverted, making it hard for them to navigate in the obstacle course : Manipulate the physics engine of the game to change the direction of gravity, there are a lot of cool resources on the dev forum that can help you with this.
Shrinking: players’ character models are scaled down, making it harder for them to reach certain obstacles or pass through tight spaces : Manipulate player’s character’s scale.
Confusing map: a map of the obstacle course is provided but with all elements scrambled, making it hard for them to identify the path : This could be achieved by manipulating the map of the game, to scramble the elements on the map. This could be done by using a script to randomly rearrange the elements on the map, or by using a plugin that allows for randomized maps.
Distorted sound: sound effects of the obstacle course are distorted, making it hard for players to know where they are or what’s coming next : Manipulate sound effects by applying effects like reverb, echo, or distortion
Blackout: players’ vision is completely blacked out and they have to rely on sounds and other sensory cues to complete the obstacle course : Apply black overlay on top of player’s screen to obscure vision completely (cheaper version of nuke.
