Tower defense stripped to its decision core: six units, one soul-collecting Shiba Inu, 30 waves, and a deceptively sharp attack-versus-training tradeoff that will cost you a run if you stop paying attention.

I do not often pick up a tower defense game expecting a resource-timing puzzle, but Soul Dog TD delivers exactly that under a very casual surface. The whole premise is built around six pre-placed units that you toggle between Attack Mode (auto-fight) and Training Mode (gain EXP, stop fighting), while separately dispatching the Inugami - a Shiba Inu spirit dog named Shizu - to vacuum up souls that enemies drop before they evaporate. Collecting those souls freezes all your units. Send Shizu at the wrong moment and a wave tears through uncontested. That single mechanic, which sounds trivial on paper, generates a constant low-level tension that keeps the pace tight across each 30-minute run. The strategic layer is slimmer than what I usually track in a spreadsheet, but it is genuinely present. When enough souls are banked you choose one of three randomized Soul Boons - buffs that raise unit attack, restore HP, boost Shizu's speed, or trigger a class-up on any unit sitting at Level 5. Class-ups are the real escalation lever: a Level 5 unit promoted to a higher tier hits meaningfully harder, so your mid-run priority shifts toward cycling units through Training Mode efficiently to unlock those promotions before the late waves spike in pressure. Battles earn currency for a separate skill tree that carries persistent improvements across runs, which gives the game a light roguelite progression loop rather than a hard reset after every attempt. The full game also ships with three selectable difficulty levels added during the 1.0 launch, which makes first-time runs less punishing while leaving harder settings for players who want to optimize soul-collection timing down to the wave. On the negative side, the content ceiling is low. Thirty waves with one map layout per stage means repeat players will memorize the enemy cadence quickly, and the skill tree fills out before novelty wears out. There is no multiplayer, no mod support, and the community discussion volume on Steam is thin. The developer is a solo creator (Libragames, one person), so do not expect frequent content drops. That said, the game earned a 94 percent positive rating across around 39 Steam reviews and was recognized in Weekly Famitsu's Gold Hall of Fame category, which for a sub-five-dollar-scale indie is a respectable signal of polish-to-scope ratio. For the strategy player who wants something to fill 20-minute gaps rather than a weekend commitment, Soul Dog TD does that job cleanly. The attack-or-train toggle and soul-timing decisions are just complex enough to reward focused play without demanding a build guide. If you are the kind of person who replays a short run trying to shave one wave off your first death, this loop will hold. If you need a deep tech tree or a sprawling map, look elsewhere.

GamerScout Verdict

Worth it for players who enjoy tight resource-timing decisions in short sessions, less so for anyone expecting deep content variety.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
