Disclaimer - I did recieve a review key for this game.
Really impressive first game from the developer, in terms of how long the game is and in terms of complexity - different mechanics used.
The developer support is great. During my playthrough I did notice a significant - and likely unintentional - difficulty spike, and offered some suggestions to make it more clear on how players could tackle these challenges. The developer implemented some of these less than 48 hours later.
Here's my video, of the pre-updated version;
and I look foward to finding the time to record and edit the new version to compare, as well as achieve the good ending.
