To be honest, I think I enjoyed WL2 more, as although this game tries to expand on what its predecessor has to offer it ultimately loses its grip on that core. Perhaps the game even suffers from being too large.

There are 25 levels, each of which you would have to revisit a minimum of four times to collect all of the treasure within it (five if going for 100%). Having to revisit each level multiple interstitial times after different upgrades are obtained (metroidvania style) often feels like a chore. You can argue that I'm pea-brained, but I don't have the capacity to remember where every specific obstacle in the game is when they're scattered throughout specific screens across several levels I last visited hours ago, which the game almost actively disincentivizes me from remembering through its design. Even if I do know where I should generally be heading, it still often devolves into aimless backtracking.

That's another thing: enemy and hazard placement within levels is almost always designed to waste your time as much as possible. While WL2 shares in this design philosophy to an extent, here it is much more aggressive. I enjoyed the puzzle aspect to finding treasures in these games where enemies/hazards are sparsely placed so you have a contained space to experiment with using or overcoming them. The same experimentative spirit arguably still exists here, but now most levels are designed to have you waste as much time as humanly possible in the process of even attempting to solve its puzzles. It turns the backtracking from a singular chore into a microcosm of chores.

I don't know why I'm this fucking incensed about a Game Boy game. In short: I didn't like it that much, unfortunately.
