This was a really cool twist to Mario and a good use of Mario.EXE idea. I enjoyed the parkour segment at the end, the plot and voice-acting for the game. It was definitely really scary to run away from the spikes as the spikes inch closer and closer to the player for every mistake that the player makes.
The game would be much cooler if the walking part was shortened as I almost thought that there was nothing at the end of the long walk before encountering the speech bubble where Luigi continues to talk about finding Mario. However, I am really interested about what else will happen to the remaining characters and if the remaining characters can defeat Mario.EXE. If the game is completed, I would love to play it as the story for the game is really intriguing.
Thank you for reading my comment and I wish you good luck in your future endeavours.
