I want to see where this is going! Nice character concept. I've just noticed, is the Molk based on a star-nosed mole?
To point a few things out:
1. About jumping responsivity - the issue is, that just checking for "jump key pressed" and "character being on the ground" is not enough for the good controls feel. There are some other things to do, like:
- If the character is still midair, and the player presses the jump key, register pressing it for a brief moment. If during this brief moment, the character is on the ground, do the jump.
- If the character was on the ground, but falls from it, register him being on the ground for a brief moment. If during this brief moment, the player presses the jump key, do the jump
2. At the moment, the game starts with the level, rather than main menu.
3. After a few jumps on the bouncy mushroom, I fell through it. Is this intended?
4. Some sprites tear. This used to really annoy me, when I was trying to fix it for my game, but, in fact, there may be an easy fix for this - sprite atlas.
