Note : so far i played levels 1 to 4
Ok i have a lot suggestions! But first somethings i liked
Very Positive:
-> The concept
-> Puzzles are pretty good!
Positive
-> I like that you guys teach via gameplay rather than just tell
-> Good variety in level design
Neither:
-> Why are the exit and back buttons different? It would nice if every option would be chosen by the same way
-> Personally felt that the difficulty curve went up too sharply. Maybe make them a little bit easier?
Negative:
-> The color of the two types of tiles are too similar. Perhaps you can make the shadow tile turn green when correct amount of shadow is on it and make the light tile turn red when there is too much shadow on it
-> I solved levels 2 and 4 by accident when moving around the lights. So i still don't know the correct solution for them. Why not add a button to verify solution instead of automatically accepting solution?
Very Negative:
-> The most annoying thing is when the level restarts. I heard from you're gameplay designer that there is a problem when the light goes inside a cube. If you can make it collide and stop instead of restarting it would be really nice. If you cant do much about the restarting then at least make it a little more clear the boundary of the light. I rage quitted in level 5 cause i kept restarting :P
Really looking forward to see where this game goes! Good job, i see great potential!
