I'm rejecting both of these hacks for the same reasons.
Level design is mostly ok. There are a couple of Core Values breaks that prevent me from accepting both of these works:

-The hack has enough time of gameplay per single run (generally, a hack of 2 short levels is not enough, though story and cutscenes will be taken into account)
-Clean use of graphics (e.g. avoiding 'cutoff', 'glitched sprites', and 'background garbage')
These are some examples of graphics not being used in a clean way.
Keep in mind that those are only some of the examples, both of those hacks are full of them. There's a lot of cutoff also in the overworld.
In the hack "YOU CAN'T JUMP" the levels are also really really short, a whole playthrought of the hack takes roughly 2 minutes without deaths, which is not enough.
The ideas in the levels are fine, if you put some more effort into the graphic work of your hacks and make levels a bit longer, with some extra care, this can be accepted.
Please, take your time with your works. Rushed hacks are guaranteed to have flaws.
