Heya, so the original plan was for each tier's first image to be bigger than the last and have a bit of a belly but due to an error on my end when i first started making the game I accidentally used the same tier one base model for everything. I do want to go back down the line and redo those images but it's low on my priority list.
As for customization/different models, no plans for that.
Thanks! I'm happy to hear you're enjoying it. :D
