I liked it, but as you said it is unforgiving. Maybe you can add a running button?

Nice game! The art is good and it is great that the look of the world changes for each stage. One wish is to have more compact maps. Anyway, I liked that the music changed for each level. Great job on completing your first game jam!

Congratulations on finishing your first game! I loved the cute style of the characters, keep it going! Interestingly enough you made very fast enemies, catching me off guard and making me jump from the chair!!  Great job on that 

sooooo cute!! the concept is really nice, well done!

Well done for your first game! I loved the concept of changing sizes between levels. Good job and good luck moving forward!

I loved the changing sizes after each completion and I'm so happy to see a game in the cellular level (for the start), it's beautifully built and a great game jam!

Considering it's your first game this is really good.

A good start to an interesting platformer I don't know if you plan to continue this project but I noticed enemies would change sizes an interesting power up for the main character would be for him to grow and evolve to beat stronger and stronger germs!!
