I miss knowing the background story and the objective of the game. I kept getting killed by the ghost, and I am not able to go through / pick up seahorses always, perhaps it is a bug?

It wasn't very clear what the objective of the game was.  I guessing I was suppose to collect the objects on the board, but there were times were I was sure I collected all of them and the game continued, while other times I only collected a couple and was told I won, and at least once I was told I won without collecting anything.  I think what might be happening is it doesn't fully reset between games, so if I get hit by the enemy with only a few left to collect, and then collect them on the next round I get the "you win" screen, even if I didn't collect everything that round.  

The screen size is rather small, which made playing difficult.  The collisions also seemed a little off, as sometimes I got caught on a wall or corner when it looked like I should be able to keep moving.  This may have just been due to the size of the screen, and missing a bit of the wall, but it wasn't very clear, which made the game a bit frustrating.

Quite good for a 3-day effort. One thing I'd work on a bit more are collisions. It's a high speed chase and it's too easy to get stuck on walls/corners. Also the enemy collider is too large. It catches you before even visually touching you.

Not bad. But it's missing a proper ending. Maybe add a timer

Is it just me, or is the “Press A To Start” button not working?

Unfortunately, I can't start the game and am stuck at the prompt :(
