Miner Madness

It would be a decent attempt at a basic platformer if the collision wasn't so dodgy. You really need to figure out how to fix that since it's such an apparent issue. Try making sure the player has a consistent collision mask. Outside of that I would recommend increasing the gravity as the game currently feels very floaty.

Though the the graphics could do with a bit more polish, they have an interesting style to them. I really like the voices, too. The music is pretty good as well, but it shouldn't restart at the beginning of every level.

This game is pretty bad, slightly below average art and ok sounds, with really below average stability.

The bad collisions completely ruin the experience, and everything feels really clumsy, from the movement to the enemy placements.

What you would probably need to make this game better is some polish, make the whole experience feel a little more pleasing and you'll go a long way.

Definitely start with the collisions though, those make the game almost unplayable.

Yeah, you could get stuck on the ceilings but also on the walls. Have you checked player mask is not same as sprite animation? This game felt like made by person who is beginner to Game maker as game engine-wise. I liked that you have made graphics other than as pixel art, it gives more unique style. Though of course it does need improvements overall, the player looks good may be. The music was good to have, though the sound effects should have been toned little bit down to same level as the music. They were now little bit too loud, but good that you had any. Game was really basic platformer by the core, collect items, avoid enemies and reach end. I did not reach the end of the game, as I got stuck couple of times, which caused bit frustration as I got game over because of them.
