I did enjoy playing and think it has good potential, but here are some suggestions if I may:
- Its challenging but because main character moves slowly it may be a bit annoying after several tries;
- I like the effort on the level design and like the look & feel of these background sprites, but the problem is some players might get confused and think they can actually land on some of these while they will just fall down;
- Adding a coyote time jump would probably avoid frustration;
Also I did enjoy a lot the audio and the effort you put into it. Really feels like a Nokia 3310 game ^^
