In Heart problems you control Iker, who lives with his uncle and his family (your aunt-in-law and their daughters). His mother left him with them at age 12 with no apparent explanation and since then he has not heard from her. He have just arrived home after a semester at college and from here the story unfolds.

New chapter added: Chapter 10.
Gallery updated with all new scenes from Chapter 10.
Improved visual quality in the compressed version. After testing, the best resolution for image quality vs file size is 1286x724.
New visual filters added. You can now adjust saturation, brightness, contrast, and tint (cooler/bluer or warmer/orange tones) from the Preferences menu.
New "Auto" speed option available in Chapter 10 animations. (Plays animations at randomized intervals for a more natural effect.)
Image transitions can no longer be skipped by spamming clicks. (You can still use Ctrl to skip normally.)
Fixed a bug that caused animations to play too fast on monitors with high refresh rates. (Currently fixed for Chapter 10 animations—coming to the rest soon.)
New memory usage options added to improve performance:Low ≈ 2GB RAMMedium ≈ 4GB RAMHigh ≈ 6GB RAM (This helps to store more images in ram to avoid lag in transitions and between animation transitions.)
New role system for Amelie. For example, if you set her role as “mom” a line like “Hi [relation] Amelie” will appear as just “Hi, Amelie.” If you chose “Aunt,” it would show “Hi, Aunt Amelie”.
New “Default” option added in settings-audio, which resets all audio levels to the developer’s recommended values.
The Android version now finally has a custom app icon (no more default Ren’Py icon).
