Tunnel of Doom

My first few runs in Tunnel of Doom felt like watching a genuinely interesting experiment play out in real time. Solo developer Antti Vaihia built something that most small studios wouldn't dare attempt: a top-down dungeon crawler where every room has a preparation phase before enemies arrive. You see the spawn markers on the map, you know what creature types are coming, and you get to decide when the wave starts. That pause before the storm - stacking low wooden walls to funnel skeletons, dropping a stone cannon at a chokepoint, checking if your pickaxe or your revolver is the smarter play - is the heart of the game, and in those moments it genuinely sings. The toolbox is wider than it first appears. Angel carries a pickaxe for close-range work, but the mine itself is a scavengeable arsenal: smash a lamp crate and you have thrown glass, crack a rock and you have ammunition, find a cache and you might walk away with TNT or a rifle. Turret variety runs from basic wooden bolt launchers to glass throwers, stone cannons with knockback, and fire turrets, each requiring the resources you gather in exploration rooms. Fifty perks randomize across runs, nudging your approach toward cannon-heavy fortresses one attempt and aggressive melee rushes the next. There is also a wrinkle unique to this game: injured miners scattered through the dungeon can be killed by enemy waves, and when one dies Angel loses health proportionally - meaning you are defending multiple positions, not just yourself. That single mechanic adds more tension than anything else on the roster. Where the game goes soft is in variety and depth. The three story dungeons span roughly two hours on a first clear, and the randomized elements - map layout, available perks, resource quantities - do not shuffle enough to disguise how similar back-to-back runs feel. The tower defense side is the weaker half: towers are balanced to be universally viable, which removes the counterplay thinking that makes the genre satisfying. You can work out a single reliable funneling strategy early and lean on it for the entire story mode without needing to revise it much. Doomed Mode (a harder version of the campaign) and Dream Mode (a procedural endless run where enemy health scales every fifteen rooms) unlock after your first win and add genuine challenge, but they are building on a core that already feels thin. The soundtrack, a spare three-track loop cycling between a combat pulse, a suspenseful prep theme, and a quiet exploration piece, does mood work above its weight class even if it repeats far too quickly. Visually the pixel work is clean and readable - every enemy, trap, and obstacle is visually distinct - though the mine setting means you are staring at the same palette for the entire runtime. Honestly, the Steam rating hovering around 62 percent positive (from a small sample) is probably fair. This is a game that holds together better than it should for a one-person project, and the concept has real potential that the current content budget cannot fully realize. If you are the kind of player who enjoys figuring out a game's logic at low cost, Tunnel of Doom can be that for an evening. If you need the roguelite loop to have legs across twenty hours, this mine collapses well before then. Kai, Scout Team
