The sprites in this game look really nice, I adore how the main character looks! The level sprites could get some work in some more blockier areas, but overall I'd say they look good as well.
The controls were also good, I liked the dash, and I think if it could be combined with the jump for long jumps, or being able to use it on air would be goated! Other nitpick i have with the controls, but i guess this one depends on how precise you are going for with the jump, but i think cutting the whole y velocity on jump key release feels a bit weird, i think if you cut if by half instead of setting it to 0 would feel a bit smoother, since you would not abruptly stop going up, but you would also not go as further.
Combat was also nice, i liked the special attack animation with the golem guy. I found the enemies to be a bit hard to hit, felt like i had to get real close to hit them, I think if the attack hitbox was bigger, it would feel better.
Also liked how the golem boss sprite looked, a bit sad I didn't get to see it moving, but that's just one of the things about making the game for the jam, time gets short :')
ANYWAYS, I liked this one, good job!
