Thank you for the in depth feedback!
Yeah we felt a lot of this ourselves the closer we got to the end but it was too close to the deadline and we just wanted to have a playable game at least. I think we fell into the trap of 'more space means more gameplay time'. Which we now know is not the way too go. Definitely learned a lot for our first game which we are going to take with us into future projects!
Optimisation is still also something I'm learning as I'm going, we did remove a lot of the lights at the end but evidently it wasn't enough.
Overall I don't think we did too bad for just 2 of us!
And I will for sure check out your game and thanks again for the feedback!
