Odd choice to not make it so game could be full screen
Using the arrows for changing the size of the level was interesting but in some sizes the tiles don't spawn, there either black or just not there (collision is still there)
Art style is cute
I feel you should have had somewhere (either the settings or the ui) the level number
Odd that not all levels use <> scale and some only use ^v
And obviously the only sound was on death
