I've finally had a chance to look at and play the game at length. Overall, I find the game entertaining with a good replay value. That said I do have a few suggestions on the interface and play structure of the game itself:
Title screen / Options menu
Based on other Intellivision games, I was surprised to find that the Enter key brings me to an options page. I would expect that one would traverse to this page either through an option on the title screen or through a different key press (maybe the '0' key).
Generally, I expect the Enter key to advance one through the interface of the game. In this case: starting the game, either at the highest difficulty level or with default settings.
Related to the above, I also expected that pressing the Enter key with the 'Exit' option selected on the Options screen would take me back to the title screen and apply the selections I made.
You may also want to indicate on the title screen what key one needs to press to start the game
From the graphic displayed on the title screen, it's hard to tell what the actual name of the game is.
I'm conflicted on how the game controls. For some of the mazes, a control behavior that mimics Pac-Man would be more desirable. If you're not familiar, Pac-Man starts in a direction and continues in a direction until he hits a wall. If you press a direction before hitting a wall, Pac-Man will move in that direction when the opportunity presents itself and then continues in that direction until he hits a wall, etc. This scheme would work best for early mazes but isn't necessarily the best for later ones, where the current scheme works better.
Maybe provide an option for this and let the user choose?
Some of the boards are hard to see based on the color combinations chosen. The corn maze and the undersea ones are good examples of this. The colors should compliment each other without being garish or overpowering and also need to be different enough to allow one to easily identify the main character and adversaries. This should be no problem on a system with 16 available colors, right?
When pausing the game, I would expect one would be able to resume the game buy pressing any key on the keypad, a side button or the disc. I shouldn't have to press 1&9 to resume.
Currently, there isn't a way to avoid an enemy when it is tailing you. The enemy is always faster, almost always leading to the loss of a life. Maybe adjust the mazes so there's always at least one nook where on can possibly duck into to avoid an enemy
When one clears a level, it isn't always obvious where the exit is. Maybe add a flashing tile for the exit, ala Boulderdash to make it more defined?
When a game is over, it would be better to display a 'Game Over' message on the last screen one was on. If one presses a key or the disc once the game is complete, one should be taken to a high score table screen or back to the title screen
In regards to the above, it would be nice to include a high score table for the game. If that's not possible, it would be nice to have the high score displayed for that play session on the title screen.
The enemies seem to fast from the start. Maybe throttle the speed of the enemies as one progresses through the game?
Also, enemies don't seem to have a set pattern for pursuing Pea-man. Is this intentional?
I hope you don't take the above as a slight to your game. I'm happy to be a part of the testing and am trying to help make the game the best it can be.
If you have any questions, please feel free to DM me.
Thank you for the opportunity to test the game and for providing me with a fun distraction from the daily grind.
