Obviously a 3d modelling software isn’t a great place to develop a ‘proper’ game, but making little toys like this can be a fun way to learn and develop things that come in handy later.
I often make silly tests as I’m developing Kangaroo.
This was when I was testing out the new SoftBodyCollide goal, but it actually lead me to notice a bug in the shell bending that I might not otherwise have spotted, so even messing around with stupid things like this can sometimes lead to improvements in the more serious uses of tools, or in the skills you are developing.
