Hey! Thank you for playing and for you feedback!
Sorry for taking so long to reply, I have been working hard on the post-jam version of the game.
I completely agree with your comment. The original jam version had some problems, especially with player movement and Lab Shape placement.
I have uploaded a post-jam version that improves on both of this points, includes changes to the original levels, adds a couple levels to smooth out the difficulty curve and adds some quality of life changes to improve the user experience.
If you want and have time, you can play it or download it from this game's page.
Keep in mind, it's still a work in progress and more changes and levels are coming, but I would like to get your feedback on the progress so far!
