Thanks for the feedback but it'd be lovely for us to hear more on what you mean by "Review the errors that appear in console". Since our first playtest sessions, it's the first time we get this kind of feedback related to running performance of the game. 

We'd love to understand what's going on. What browser do you running the game on? At what part of the game, if any, especially you get those freeze problems?

Thanks for giving it a chance, we hope it gets indexed on itch so we can collect more feedback on both how the game feels and how ingame balance is.
