Hi all!
First off we want to thank you for your amazing support and feedback! We've been collecting your reports and doing what we can to improve the game!
There were a lot of performance optimization changes to be done, and still a few major ones to be ironed out, but don't worry, we aren't stopping development just yet! We will continue to work on the game for the next week, until our graduation and this game's due date (this is a student game, after all!).
We also fixed the achievement bugs, and a few other glitches. Just like with the optimization, a few remain that we want to cover. However, having seen the feedback from some of you who like to speedrun the game, so we will keep most or all of the "bugs" which are conducive to speedrunning, so long as they don't cause other issues!
Thank you again all! And please let us know of any continued problems and we will do our best to address it.
