I LOVE these sorts of fun creative games where you basically get a toolbox and design elements, and they let you loose to play with them. I also think the job feature is pretty genius, as I know not everyone like that 'loose' type of gameplay as much, and for those people creating pumpkins for clients (probably) works really well!
I'm impressed with all the different edit tools you managed to squeeze in, and they all work solidly, including the selection/deselection of objects (that's pretty notorious to code because of a lot of potential edge cases). The only thing that I'd love to have in addition to these is a duplicate function, as sometimes you've spent time adjusting an item and want to duplicate it.
Unfortunately every time I pressed the 'save' button, the game crashed for me. Not sure what's going wrong there, I just unzipped the file and ran the .exe file. Also, is it correct that the 'carve' tab button does nothing when I click it? Is that a future feature? Maybe it's good to mention that on the page if so. Another thing that might make this game complete is some chill background music while you're working.
I thoroughly enjoyed making pumpkins and creatively using the different elements, of which there are a lot. Good job on the game, it's a simple and fun concept, executed very well. I've attached a photo of my favourite custom pumpkin. Thanks for participating, cheers!
