As a long time fan of Arkanoid, and a gamer with an appreciation for Space Invaders, this game grabbed my attention as soon as I saw it. And while I enjoy playing it and do recommend it, there are many things I would rather have seen executed differently.
First, I'm not a big fan of arbitrary time-limit based gameplay. Because they don't have time limits, both the original Arkanoid and Space Invaders (and most of their successors) can be enjoyed casually as well as obsessively. Not this game. Each level demands your rapt attention and careful precision, or else you are guaranteed to fail. I'm only about one-third of the way through the game on Normal mode, and some levels are already clearly set up in a manner requiring the player to reach the maximum allowable number of attack modes within the short time limit in order to even have a chance at victory. Which brings me to my next point:
The game offers boosts as well as special abilities during attack mode, which cost in-game currency to buy. To be clear, this game has NO MICROTRANSACTIONS after the initial purchase. The problem is, the boosts and abilities are still very "expensive." It feels like this game was initially developed as a free-to-play title, then someone made the decision to sell it as a regular game instead, but then nothing was rebalanced to account for the player's inability to pay to win. Instead, your options are to grind for the coins you desperately need, or simply play well enough to render boosts unnecessary. So far I've chosen the latter because I really don't like to grind. Fortunately, 65 levels in, I have yet to encounter any levels that are impossible without boosts.
While I'm on that subject, none of the boosts or abilities feel very useful at combating the most difficult aspect of the game: getting the ball where you need it to go in the short window of time you get with it. The initial bow-and-arrow style aiming is a nice touch, but levels quickly get away from the open type of design where it can really help. This is especially true at the point in the game I'm at, and that means even if I could afford to use the boosts, I don't think they'd really help much.
But despite all this, Arkanoid vs. Space Invaders remains a creative mash-up of two great classics. And so I ultimately do recommend it so long as the player understands the limitations of the format.
