Really simple game :D
I like the minimalist artstyle and everything is consistent so I cannot say anything bad about the art, its good!
Gameplay wise its a very basic idea where you switch between 2 different maps that interact with eachother, the idea itself is a bit uninspired i'd say, there is no unique twist to the mechanic and the execution is just okay. Sometimes you would fall and then there would just be unavoidable spikes that you could not see from the limited FOV you have, maybe a mouse where you can kind of move it a bit just so there arent thease unfair deaths.
Soundwise, I honestly do not know if this game would benefit much from sound, the game has an almost stoic level of simplicity to it and I think sounds would break the immersion, the background music is nice though.
I cannot say much bad or good about the game, its the most average game ever...
Only the unfair camera related deaths are a thing that damages the game.
you take that as you want, I personally admire the simplicity and leniency of this game, It's impressive how extremely barebones it is in a good way :P
Good job and good luck on your next projects :D
