Conceptually awesome. Been a while since I've played a tower climb game. The use of theme is interesting. The use of dice as the tower looks awesome. Being able to use the walls as platforms by breaking them was something I've never seen before and had some interesting applications.
Best feedback I can give is it feels a bit punishing even for a tower climber. The standing jump is just short of being reliable to go up levels. And if you get a platform of ones with 4s or higher above the floor disappears so quickly that it feels impossible most of the time. The keys and locks seem to be an answer to that problem but they are often to hard to reliably collect and when paired with the short jump height and a narrow opening its hard to feel like a justifiable loss, which for this genre is a key component.
Always nice to see other Gamemaker projects in these. Overall, a lot of good work. You have a solid concept and generally executed it well.
