What a fantastically wonderful game. Don't let the visuals fool you, this is a full blown metroidvania style game with a huge variety of content that I genuinely did not expect to find in a gamejam game.
There are some issues as noted in the game description so make sure you read that properly if you want to experience the game during it's current jam form. But wow what a well designed and challenging experience.
The puzzle system works really well and having to find the blocks to complete the puzzles is really cool. I have to admit my dumb*** probably took longer than it should have to complete some of the puzzles but it was worth it in the end.
I really hope this continues to develop because it has an amazing foundation of design and style that I want to see flourish.
