No doubt 5 Star. The creativity is just unbelievably limitless. The levels are well design and balanced, also you can skip to whatever level you want because all of them are unlocked initially.
In sandbox mode you can literally design whatever you want. I bet someone can design a folding rotating multi floor garage, a 1 to 1 recreation of some real world rollercoaster, maybe even a transformer. It’s like 3D printing but instead it’s instant and cost nothing.
A few suggestions:
*Level descriptions are too cryptic to understand, you should give a preview of how the cars and mechanics would move. Just let them fly through the air to demonstrate.
*Sometimes I have a wacky solution but I would like to see what’s the supposed solution. You should be able to unlock “designer’s solution” after beating a level with 3 star.
*Should have an easy way to share designs. Both between friends (copy&paste) and over the internet. Better yet, should have a community of solutions and sandboxes with likes charts maybe even player made expansion packs.
*The length restrain makes it very hard to edit designs. E.g. it’s a nightmare trying to add a bit of curve to an already made straight bridge. There should be a prototype mode where you can stretch pieces over limit but you have to fix them before running it. (If you are worrying about frustration of constantly can’t run a design, you can add an “undo until valid” button)
*If you are looking for IAP ideas, instantly unlock “unlimited budget and resource” for all levels should be a good one.
*When selecting, you don’t know which one is selected if there are multiple item at the same place, a bit inconvenient.
*It’s unnecessarily inconvenient to convert wood to steel, which happens quite often. Drawing steel on top of wood should automatically replaces it, simple quality of life change.
*The hydraulics can only extend/extract for 50% max, I know it’s mimicking real world but it’s limiting the design space a bit. Not sure if there is way around it that I haven’t figured out.
These are just some nip picking ideas, the game is still a solid 5 stars without them :)
