Wow! Thanks so much for the kind words and for checking Katspoegie out, I really appreciate it!
Apologies to hear about the performance issues your'e having, I think I accidentally forgot to enable the Graphics settings for the game, I will try to get an update out later today that will re-enable it then you should be able to set the graphics a bit lower, sorry I didn't really have enough time to concentrate much on optimization.
I am planning on doing a 2nd Prototype in a month or 2's time with new game modes, I will try to check if I can make the movement and collisions a bit less clunky then.
Thanks again so much for the support and the valuable feedback, I truly appreciate it :)
