This is a short behind-the-scenes explanation of why my game, Let’s go cave-burrowing is missing some gameplay
In the beginning I envisioned a game where you threw “grenades” to change the environment, sort of a casual-like game. I didn’t want to have any game-over screens or the like, as this would detract from the core gameplay. One solution to make it more interesting was to add diamonds that threw out more puke-like balls that exploded, though I didn’t had the time to implement it.
All the easy game-play I could add to make it more challenging would remove the fun. For example I thought to add a timer so that you had to complete the level within a certain time, but then the player would not be able to “explore” the level at his/her own pace.
It was only now this morning that I realized that the perfect solution would be to rate the player based on some score of fast-completion and huge explosions, since then it would add a challenge for those who wanted it, but it wouldn’t punish those who didn’t. I guess you can’t win every time
