I really enjoyed this! The gameplay was so well done, I loved how you made such a unique movement mechanic. The levels were exciting and had a good difficulty balance. I think you had the most creative take on the theme, I never would’ve guessed that flies could be used with “old” but yours worked great. The sound was good and I didn’t encounter any bugs (of the non-fly variety). I do wish there were more clear barriers around the edges of the level and some more variety with the backgrounds would be cool too. Other than that it’s a great game that’s really fun to play and has lots of playtime; excellent work :D
