Hi! Thanks for sharing your feedback! We really appreciate it. This game is a very very (really very! haha) early prototype. We agree there a lot of ways the game can be expanded on and that is the plan. Hopefully in the future once we have posted a few rounds of updates you will enjoy it more, we have lots of things we plan on adding :-)
Thanks for your feedback on the movement during the digging phase, that is something we plan to look at improving!
Thanks for playing!
