Wow, really appreciate this thoughtful and in-depth feedback/review of the game :D
Following the response to our game we plan to develop further and have started a dedicated devlog page over on GameJolt (https://gamejolt.com/games/two-can-do/511830). Therefore this feedback is really helpful in allowing us to improve the game and produce a better product.
Audio will be on of the first things we re-work. With only 10 hours of jam time available to us we ran things quite tight and were frantically adding audio in the last 5 minutes, hence the lack of sound effects. Non-looping music was just us forgetting to tick the loop box whilst rushing to meet the deadline XD.
We really like the suggestions regarding animations and agree that they would add a lot more feel to the game. Again, we plan to revisit these in the near future adding more animations and re-working the existing ones.
Thank you for taking the time to play our game and providing such valuable feedback. We're glad you enjoyed it!
