Congratulations on finishing your first game with Game Maker Studio! Here's my feedback:
First: the positive. Overall, I think the mechanical idea you went for was implemented properly. The game runs smoothly and it's clear what you have to do to beat each level.
Now, the negative: I can't give this game a great rating because I don't like the way you tackled the theme of the game jam. Pacman's ability to devour ghosts is part of what makes Pacman so fun to play. When you take that ability away, it doesn't make Pacman more fun or interesting to play. It only slightly increases the difficulty and makes the game more frustrating. Whenever I collected a cherry, I found myself frustrated that I wasn't able to eat the ghost.
Please, don't be discouraged by my criticism (or by my rating). It's clear that you have the development skills to produce a game, and I think you should be proud of the fact that you made a functional Pacman clone. However, I think your design choices could have been better, and I think that will get better as you gain more experience.
Rated 2/5
