Hey, overall a great gaming experience, the graphics look great and with sound it's sure to be twice as good. The puzzles are a bit simple at times but it feels pretty good to complete them.
I think my comments are focused on the technical aspect and even they are details that are not polished because it is a demo, but I think that saying them out loud will help to take into account those small details while the final version is being developed.
- in hub the reload icon grow indefinitely when pressing the reload key.
- The aim goes behind some element (hub doors as example), i think it should be always in front of all other elements (stoping in walls and collision objects of course).
- option 'show icons on magnets and fields' only applied to magnet not fo the icons flowing in the magnetic zones
- if the game is already set in fullscreen, when exit the game and start again it will start in fullscreen and the 'fullscreen' button will toggle to window instead of fullscreen.
- You can pass the magnet through the area without magnets if:
1. you leave the magnet just on the outer edge of the area without magnets.
2. You put the character right on the inner edge of the area without magnets.
3. Take the magnet and throw it as fast as possible before the zone makes it disappear.
- From a personal point of view I feel that the design of the tubes is a bit out of place with the industrial/metallic environment, maybe metal tubes would be more in line.
- The character moves well but I think that the possibility of "running" would improve the experience, especially when you get stuck in a level and have to do everything again.
You are doing an excelent job!
