There's not much to say about Tunnel Escape. It's a simple Turn-based combat game where failure leads to an H-scene. Nothing new, nothing innovative.
However, what makes Tunnel Escape stand out are the H-scenes. The Japanese 2D anime art style images make it the perfect fap material. The quality is better than most of its competitors. The character has an amazing body with perfect proportions without her breasts being bloated or ass being ballooned for no reason.
The sex scenes are 99% static images with 1% moving parts. There's heavy reuse of assets so often you'll see the same images over and over. There is no variety of sex scenes within the same enemy archetype, so once you've been defeated by a particular enemy, that's all there is to see. They don't take different positions, nor do they don't do anything different.
The Teddy Bear has the best H-scene so far, as it latches on to the character and suckles on her tit while the character makes erotic faces. For a game so focused on horny enemies, there is not enough breast play. Only two out of all the enemies actively grope breasts during a fight. The rest skip directly to her vagina and start inserting their knobs in her.
I certainly liked the Hymen system. The blood trickling down her thighs leaves an impact on the player, reminding her of the defeat she faced. The blood can be inconsistent and sometimes won't appear even though she was a virgin. It's very easy to lose it to a boss fight if you're not careful, but there isn't any advantage or disadvantage of doing a virgin run.
Only a few sex scenes show penetration, but the rest do it outside of the camera's angle, leaving the rest to your imagination. The lack of sex positions and camera angles is damning, as most enemies only have one set of images, and it gets boring after you've seen it twice.
The game behaves like a roguelite and defeat means doing the level completely over again. No checkpoints or autosaves. You'll undoubtedly be forced to replay levels multiple times to get better gear, grind XP and unlock perks. All of this adds to the grind, and yes, the game can be very grindy.
Ultimately, the game reminds me a lot of 'Parasite in the City'. You can see the similarities and even some of the H-scenes are directly inspired by that game. Sadly, both games commit the same mistake, they cheap out on the artist and reuse assets all the time.
Overall, it's nothing ground-breaking and the anime images get old fast... Still, the game is worth giving a try. To skip the grind, use MTool.
