I had a great time playing the game and really loved the retro vibes. The levels were both challenging and enjoyable!
However, I encountered a minor issue in the initial demo area where I got stuck multiple times due to the yellow cube being trapped. The room got locked when I picked it up from other room, making it impossible for me to retrieve the cube and forcing me to restart the game.
This issue:
The view of the final level (3) featuring a pier and a lighthouse was quite impressive.
Certainly worth playing!
