Pixel Jumper

This is a platformer game with 10 levels. In each level, you need to collect 10 apples and reach the trophy to move on. There are also two types of enemies: an astronaut who deals 1 heart of damage, and a pink guy who deals 3 hearts. If you approach them from the side, you'll get hurt, but if you jump on them from above, you'll defeat them. Watch out for holes you can fall into! (The game is in Polish)
