This was a really interesting concept to play with.
I really did like the overall gameplay and I did enjoy it, the upgrades were quite nice.
However I do think some addition of a UI/UX could have been nice, as I did not know what to do for the first 3 minutes. Which is partially on me tbf.
The ladders are a bit weird to get on as well, the number 10 is in particular difficult to do with just the ladders.
Maybe some Bg audio could have been added but that's not too big an issue tbh.
Apart from that - This was fun.
