Loved your game, the graphics are well designed for a game Jam and the overall idea and the gameplay feel very interesting. But there  is one visual, an audio and one game bug. When it says enemys strength is increased by 2, it is actually increased by 1, you cannot deactivate the sound and music by clicking on the icons, even though it seems like you should be able to, and for the game bug: it is possible to get infinite health, by decreasing the strength of the enemy below 0, so it gives you live, when the enemy attacks you. Otherwise the game is really creative and I hope the game gets developed further with more variety in leveldesign.
