Beautiful game. 

Fun game! The throwing mechanic felt nice, though I found myself sometimes placing stuff down when I wanted to throw it.
Mechanics were all solid, and had a good NES feel to them.
Enemy placement really seemed to reinforce a slow and methodical approach to things, and that combined with the permanent health loss and how long it can take to grind out upgrades did make it a bit rough.
I don't know if I'd had it in me to start from the beginning the third time, but thankfully managed to beat it on my second attempt going.
Sound design was great though, really enjoyed the music.
Story bits were nice, that ending text though, wow
All in all, very solid, would recommend to anyone having trouble to pick up the shield upgrade soon as possible. Didn't realize what it did at first.

Valu's Impulse was definitely fun but also very difficult. The challenge was engaging, but I wish there was a "Continue" option instead of restarting from level 1 each time. I would have loved to keep going and try to beat level 2 without starting over from the beginning again. It took me a while to reach lvl 2 and I didn't really want to replay it yet again

The popes with fireballs were super tough to deal with, and I found it hard to dodge their attacks. It made the game feel a bit too punishing at times. I also unlocked some traits but couldn't quite figure out how to activate them, which left me feeling a bit underpowered. For instance, I thought my fireball, or "heat" trait would give me a projectile, but I didn't notice any change. Clarifying how to use these traits would add a lot to the gameplay experience.

Despite the difficulty, I loved the graphics and thought the music fit very well with the game's atmosphere. The intro cinematic was especially impressive and added a lot to the overall presentation. Great work on that! I think with a bit of tweaking—like allowing players to continue from the current level—you could maintain the NES-level difficulty while softening the harshness just a bit. Keep up the great work!

Very pleasant. The box mechanics remind of a game "Chip 'n Dale Rescue Rangers" from 1990, feels good!

Fun game! The mechanics are all pretty well implemented with the block moving , good job

Sweet game yo

It's a very good game, one of the best of the jam, and it truly feels like an NES game.

wow! this game is incredible for how short it was made in, and i really enjoyed the level design and sfx. :)

I feel a worthless sense of pride.

The game perfectly feels like a NES game, it's fun to play with the appropriate difficulty and speed of everything, I like the music and the demon animations are specially cool in particular when he's holding the key.
