I went in expecting something a bit different from what I got, but I think it worked out well.
It's rough around the edges, especially in terms of the gameplay, but feels almost like the game is aware of it and tries to head off the worst issues at the pass. There's no real way to avoid taking damage in combat before you get a ranged attack, no real way to avoid getting hit by the boss, and it's a nightmare to try to use healing items in combat, but you have a pretty deep health reserve. Jumping feels stiff and the grapple mechanic is finicky, but there aren't any jumps in the game that require pixel perfect precision. It was surprisingly ambitious; I wasn't expecting to see an inventory or grappling at all.
I think the one exception to this is that it's pretty clearly playtested with the WASD layout and not the arrow keys. I would have preferred actions on the ZXC keys rather than being spread across the keyboard and almost requiring three hands.
The graphics are fine. I'm not a huge fan of this type of pixel art personally, but's it's fairly well executed. The audio that's in the game is good, but it's very sparse musically, and really should have menu music.
The intro feels like a bit of a shitpost, but the game feels pretty tongue-in-cheek overall so I think it fits. Not one, but two truck-kun crushing our protagonists sets the tone (was Isekai a bonus theme?). I think the one thing is that I was expecting something much more serious from the description on the page.
There are some typos and grammatical issues in the dialogue. It does feel weird having a completely different dialogue system in the intro (speech bubbles). The dialogue in game advances too slowly, but it's possible to fast-forward, so it's not a big deal.
The ending is really abrupt. I'm guessing you ran out of time?
