Thank you for the feedback, glad you enjoyed this!! We noticed a few things towards the end of the week especially the performance issues an unfortunately didn't manage to fully solve them but we knew they existed, but thank you for letting us know about them.
Thanks for this, we planned on showing the player a small introduction on how to complete the basics of the game but in the end ran out of time but this was a thing that given more time would be in the game. Also the optimisation was on list of things to do just never got around to it all.
