Retry the game playing not in full screen. We BADLY mess up resolution, no excuses for that.
The colliders needs to be redone from the ground up, we are aware of the problem.
The only thing we disagree is the 8 directions. We choose 4 directions because we was inspired by games of the NES era like Adventure of Lolo or Bomberman and we want to give that feeling.
In any case don't be afraid to be a little bit harsh, feedbacks are feedbacks. You are not judging me or the other two team members. You are talking about the game and it's problems.
We are sorry to hear that you not enjoy your time with the game but this is a very important feedback. It means that I (the programmer/designer) didn't do a good job and I need to work on it to makes people enjoy the time with my games.
Thank you for playing, sincerely.
