Fun and simple puzzle game! I think that’s a shared sentiment among the comments~
I think readability on the font is definitely a problem on this one, but that is expected on how low of a resolution you’re trying to do. A 3x4 pixel font works a lot better for this if you want to keep low res.
“Explodes in:” can be substituted with like a timer icon or a bomb icon to reduce clutter, but that is also hard to do in such a low resolution……
Also, I think there’s no surprise that there should be a full reset option, maybe a keybind for each rewind, like backspace.
Real nice game though! Well done~
