Considerations

This is a really great app. I ran into challenges registering in the online forum as there was no visible key to enter. I would prefer to post in the forum, but am doing so here. This is not a review but a response to a feature that is not working properly. Control click(multiple select) is not working on my ipad keyboard. There is no physical way to multiple select either, therefore I cannot edit the pieces in my project and manage interactions properly. This is a must fix in my opinion. Box selection does not work when you have even a slightly complicated setup. Consider adding a physical button for multiple select or better yet a keyboard shortcuts menu. A lasso tool might work too. Thanks for listening.

Great physics sandbox

Has all the tools required to make basic physics simulstions

Algodoo

I can’t enter the Home Screen anymore please fix it to make it work for ipadOS 26

Most good, some bad

The game isn’t the best I’ve seen, however it is pretty educational and fun, however there is a problem where sometimes it just kicks me off, and doesn’t save me progress on a build. And another thing, sometimes my most recent save file loads and isn’t there, it’s just the default background but no builds at all, apart from these minor inconveniences, I generally like the game for its uniqueness and how you can create basically anything and everything. 4/5 stars 👍
