Thanks for playing and for your kind reviews !
Yeah, so actually here is what happens : when clicking on the chair, you're trying to reach an unreachable point (I should have made the whole area unreachable it's my bad...). When the navmesh agent is moving, everything else is deactivated (to avoid bugs...). And sooo you're stuck ! So sorry for that...
Yeah I feel you on the screen problematic, it was a quick fix to an unwanted bug aha
Thanks a lot for your feedback !
