ok
i think i have an idea on how you could fix the collision mapping
you could create a grid
like so:
Each cell of the grid in this example is 21 x 21 pixels. You could have an array of integers in memory where 0 means you can't enter that cell, 1 means you can, 2 is a regular pill, and 3 is a power pill and 4 means a ghost is in that cell. Something like the following:
int[,] grid = {{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 2, 2, 2, 2, 2, 2, 2, 2, 0, 2, 2, 2, 2, 2, 2, 2, 2, 0, 0},
{0, 0, 3, 0, 0, 2, 0, 0, 0, 2, 0, 2, 0, 0, 0, 2, 0, 0, 3, 0, 0},
{0, 0, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 0, 0},
{0, 0, 2, 0, 0, 2, 0, 2, 0, 0, 0, 0, 0, 2, 0, 2, 0, 0, 2, 0, 0},
{0, 0, 2, 2, 2, 2, 0, 2, 2, 2, 0, 2, 2, 2, 0, 2, 2, 2, 2, 0, 0},
{0, 0, 0, 0, 0, 2, 0, 0, 0, 1, 0, 1, 0, 0, 0, 2, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 2, 0, 1, 1, 1, 4, 1, 1, 1, 0, 2, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 2, 0, 1, 0, 0, 0, 0, 0, 1, 0, 2, 0, 0, 0, 0, 0},
{1, 1, 1, 1, 1, 2, 1, 1, 0, 0, 0, 0, 0, 1, 1, 2, 1, 1, 1, 1, 1},
etc.
you could create map editor for your maze game
this would resolve the problem of too tight of spaces and
the dots not being in the right spots
