itch.io

For me it was  18-20 hours total, around 3 hours a day and 6 hours on 25th. I started a bit late, on the 22nd and with no prior game development experience, I am happy with what I was able to achieve in short period of time.

Tried it few times, had a fun experience. 

Only negative is that at later stage red background particle flashing was messing with my eyes.
