Quite fun! Though I keep running off the edge lol. Poor grandpa :'(
It reminds me a bit of those mobile game ads that look fun but you knooow aren't what the actual game is
Just a little side note, it would be better if the controls were consistent, so either clicking the boxes and clicking restart or pressing some keys for the actions and pressing R for restart. Also a pause button would be nice
In general, it's pretty fun. Good job!
