Though I'm saying I don't recommend it, I will say that this title has interesting ideas and it executes some of them well. However, it has glaring issues that prevent it from being truly enjoyable. As of this writing, I've beaten three of the offered games, with one of the others being a card game which has no end and one being a hack and slash gauntlet-type deal that's based more on high-score than completion. The other two I have no intention of finishing.
There are seven games featured here, but each will last you only about an hour to an hour and a half from start to finish. Which is pretty cool, I'd pay 50 dollars for seven hours worth of quality content. However, this leads to the issue of none of the games really 'sticking' with you, with one solid exception. I'll give a brief overview of each of the games without spoiling any content, as best I can:
-An open-world platformer where you grow into a stronger creature to get more powers to access new areas. This is a cute title, where progression is easy and a puzzle element is mixed in. However, in order to grow, you need to eat smaller enemies. These don't respawn until you have eaten every single enemy in the area, which is annoying. The open world is solid, but the game moves at a rather casual pace. Imagine a combination of Super Meat Boy and VVVVVV, only walking a bit slower and with flutter-jump mechanics as opposed to gravity or speed wall-hopping. Good intentions are here but they don't all come together, and the slower pace of the title really shoots it in the foot.
-An action-puzzle game ala Adventures of Lolo, wherein you have to eliminate all enemies and then kill yourself. This is a nicely built game, kind of a Mega Man vibe to the graphics and soundtrack. The issue I find is that, simply, you can easily put yourself in an unwinnable scenario later on. The joy of puzzles is figuring out the next step, not repeating previous steps, which would require a minute or so to recreate. It's a good concept and if you like the Eggerland series, this one won't do you wrong, just not my cup of tea compared to good ol' Lolo.
-An arcade action game where you beat things up. It feels good and responsive, hitboxes are fairly solid if strict. Not a lot of depth to it, I felt, but it's a fun distraction.
-An open-world platformer that's pretty much 'hey we wanted to make a Metroid thing. Here's some Metroid for you'. Honestly it has a very clever concept, wherein there are three overworld maps and you warp between them as different 'time periods', making for a very well thought-out map system. The issue is that, unfortunately, the game is dull. There is no sense of danger, very few enemy types, only two boss battles (which are both very easy), and no real environmental hazards outside of a few rooms. This leaves for a very barren-feeling map, as opposed to a Metroid title, where lava, various terrain obstacles, and a variety of enemies kept the player engaged. It's... rather dull work, honestly. Which is a shame, as the core controls are very good.
-An arcade platformer similar in vein to Donkey Kong and Donkey Kong Jr, wherein you're a helpless creature who has to use the environment to get past obstacles. There's some clever concepts, but like the afformentioned DK games, the main character moves at a snail's pace and can't survive long jumps. This makes repeating segments unbearably slow. Unlike DK and Son, additionally, enemies follow set patterns, so there's no element of action or randomness to react to; it's just figuring out the puzzle and hoping you're fast enough to do it. It was fun through the start, and the graphics and style and undeniably charming, but it grates and I doubt many will finish this segment.
-A card game. Frankly, it's just a unique concept that doesn't pan out due to being a single-player card game that you likely won't be asking a friend to play with you.
-A vertical shooter set in feudal Japan. If there's a game that's worth your money, it's this one. Different enemies giving different types of shots, being able to reflect enemy fire with quick enough reflexes, an upgrade system, managing your special weapon types, and reasonable enemy placement. It's a bit on the easy side, but mechanics are well thought out and constantly engaging. Easily the best of the bunch.
The issue with Retro Game Crunch is that it's a game that doesn't quite live up to its potential. It's very solid, but for a fifteen dollar asking price and competition as stiff as VVVVVV, Meat Boy, and Eversion for 'simple concepts harkining to a retro time period', it really does not hold up. If this game goes to $5 on a sale, I'd say it's worth your time. Odds are one will appeal to you, and that one might even be really good. But I'd wait until then, and not jump on a 50% off - wait for the lower. I love retro games, the entire retro vibe, and I want to see more from this developer, they're smart people. This outing just leaves a poor taste in my mouth at the end, unfortunately.
