First off, thank you for playing our game! We had a lot of fun making it!
Currently, there is no end condition, so the only way to restart is to reload like you said.
We've got some bug-fixes in the pipelines that address the camera issue (among others). We also will be improving the UI (menus, scoring, and some new mechanics too) which will allow players to play many rounds instead of having to reset completely. Finally, we've been brainstorming some quests/goals to add to the game to make it more of a challenge and less a sandbox.
Stay tuned!
P.S. The update will probably have to wait until after the 48+8 Jam ends in order to be fair with other contestants.
