Eroico is... genuinely a great game. Being the follow-up of Kurovadis, Kyrieru really took a lot of lessons and improve this game in every way possible, leading to this magnificent piece. It is without its flaws but I think it still deserve immense praise for what it managed to do.
~Art: a major upgrade from Kurovadis, the pixel art in this game is amazing. It's lively, well animated and it has this very arcade-like feeling to it. Everything from your character, the enemies, the background and especially the effects are super well-done.
~Sounds: super duper satisfying. Every actions from attacking, blocking, dashing, enemy death effects, etc. All of them compliments the gameplay a lot. And the OST, oh the soundtrack, the songs BANGS. It is worth mentioning that both Kurovadis and Eroico's soundtrack was composed by Kyrieru themself too, so this is honestly an amazing job for a pixel artist to handle both the music and the sprites in such an astonishing way.
~Gameplay: now this is PEAK. This game honestly succeed in being a proper game, as it is REALLY good at being an action platformer.
-Your arsenal of mobility and offense: there is a lot to explore in this game, even beyond the surface. You have 3 buttons: attack, block and backdash. You actually have lots of attacks: up + attack is your projectile (requires a limited bar), down + attack in the air, down + down in the air is a downward thrust and down -> forward + attack is horizontal thrust (damn, we playing Street Fighter?). You have a lot of options BUT that's not all because you can cancel your backdash into ANYTHING (but walking), including normal attack AND you can cancel your normal attack into backdash which means this game has some advanced tech. I love advanced stuff, even in these H-games, they make the game so much deeper and more fun, and Eroico is full of that. I am barely scratching the surface because this game have some very nutty stuff you can pull off, and I'm all for it! The more you play this game, the more you'll notice how hard but rewarding it is to master the game's movement and simple combat, it add more layers to such a simple system like this.
-The enemies and the stages with them: stage design and enemies placements is nothing short of phenomenal. The platforms, the parkours and the mix of enemies inbetween really makes this game challenging. The enemies themselves are great, each are simple and only gets mildly more complex as you play but still create enough challenges when you combine multiple of them in one room. The synergies between each of them is crazy, setting up new obstacles to overcome by simply putting two different enemy types or heck, 2-4 of the same enemy in one screen. And outside of the enemies, the stage design of this game is out of this world. Each world and each screen have bits of alternative paths to get some extra power and health, from time to time, you'll meet some parkour obstacles which is really fun to figure out and go through. Combine that with the jolly amazing and deep movement mechanics and you have one of the best platforming sections out of an H-game. It's this mix of both stage challenge and enemy challenge that makes this game and Kurovadis really unique.
-Bosses are cool: there are three worlds, which in turn means three bosses, each come in their own flavor. All three are amazingly designed, the first being a rushdown, high octane fight which really pumps your blood. The second requires some real patience and the third is just a mini-bullet hell, you will dodge a lot of b a l l s. I had a lot of fun beating all three with no-hit, and usually that means the boss are well-made, not boring and is actually fun to fight against.
-Difficulty: now I think that this game isn't easy. Eroico is quite brutal, and takes some time to truly "master". Even so, the easiest difficulty is not the hardest thing in the world for casual players, I really recommend that for beginners because whew, this game is really really hard.
~H-scenes: the scenes and CGs are great. I love how well-animated they are, like every other part of the game and the CGs are just images but I give a solid thumbs up too. Although, the game really lacks some sex mechanics, being that it's the simple "get beaten and get sex scenes" again. This game gets a big plus over Kurovadis though, 'cause it has an actual gallery mode this time, woohoo. Only problem is this game is hard to beat, so you aren't getting a giant gallery to compliment your journey.
~Misc.: the game has more quality of life features than Kurovadis, but I'll say it's still lacking. Screen resolution still just make everything blurry. Story is non-existent though it is simple enough and can be understood easily so it gets a pass.
~Conclusion: the game is just an amazing game, although it isn't a perfect H-game. It is missing a lot of H aspects, but it hits the game part really hard. Recommend this to anyone looking for a decent challenge and an amazing platformer to go through, if you want some quick H-scenes, sorry you're out of luck. 9.5/10.
