Good title. Bonus points for that. I love that the main guy is BUILT to SCALE walls. That got me hyped right away! Plus his little stupid simple face on top of his jacked Baki-esque musculature is beautiful. The little details were truly golden like the cheers lifting up the gate. The premise and presentation were absolutely golden, even if I'd be happy to live the rest of my life without another Kevin MacLeod song. But what's there is really good, no complains in the graphics or sound department, it works and it's charming in its own idiosyncratic way.
Gameplay-wise, the premise is great, but the execution leaves lots of room to be desired. I finished the game after some persistence but it honestly felt like a coin toss if I could by the 3rd castle. Because you're so beefy, it seems like your hitbox is pretty large (even if it necessarily isn't), but more importantly, there's not enough time or screen space to easily dodge projectiles.
The camera could have the player at the bottom of the screen to give them more dodging room, or simply zoom out, slow the projectiles, etc. You can't be fast enough to act, and if you are, the button mashing controls make it difficult to navigate smoothly and intuitively. I mostly just made a mad dash mashing the keys and screaming like a maniac praying I wouldn't hit anything like how people in the olden times would drive AT FULL SPEED AHEAD in pedestrian main streets, basically just not slowing down for anything. Because if I did, it was sluggish and there wasn't enough of a heads up to act quickly or smoothly. It felt like psychological torture not knowing how high up you were (or at least I couldn't, maybe the HUD told you but I was too panicked to figure that out in the moment)
But because it was short, and it was just fun to look at and mess around with mechanically climbing like Spider-Man on speed, I persisted after dying about 4 or 5 times. Fun stuff, I could easily see a polished version of this playing as a well-placed mini-game or something on mobile.
