Alchemania

Visually, the game is a delight. The graphics are colorful and whimsical, creating a captivating world of alchemy and magic. The attention to detail in the potion-making process and the diverse magical ingredients adds a layer of charm to the overall aesthetic. It's evident that the developers put thought into making the visuals both visually appealing and thematically consistent.
The gameplay of "Alchemania" is where it truly excels. Mixing potions and experimenting with different ingredients is surprisingly addictive. The controls are intuitive, and the learning curve is well-balanced, making it easy for players to grasp the mechanics while still offering a challenge. The sense of accomplishment when creating a perfect potion is immensely satisfying.

Yeah so I'm writing this review after 15 minutes, but don't go and make a conclusion.
It's only because the reason that you complete the game after this amount of time.
You're going through 35 easy levels and you are done.
Actually you can finish it couple minutes before if you aren't trying to get all 9 soul gems for completing the achievements, but don't mind that right now.
Altogether the game is fine for me, no further. 2D Pixeled platformer runner game.
Well. the only things I liked in the game are:

The Character.

Suggestion - add different difficulties

The completion of game took me around 15 minutes and it was pretty interesting. The structure is very easy and levels are not that hard. Remember to take all the gems before passing the missions that include them if you care about achievements just like me ;) If you fail, you will need to complete the whole game one more time.
