Nicely made. I've never played the original, but it looks/sounds familiar.
The core concept here is solid, but I think the level design is a little too involved. The slow pacing of the game makes levels take a long time and most of that time is just moving without needing to worry about the enemies. I think shorter, more concise levels (and maybe a slightly faster game pace) could make this a lot more engaging. The need to completely retrace my steps for some of the coins felt taxing instead of engaging.
The rest of the game is great. The actually puzzley moments when you're being pursued by multiple enemies is a lot of fun. I'd just like to see more focus on that and less on large levels that require backtracking to find an exit on the opposite side.
Congrats on finishing this in a weekend! Plays and controls great!
