Nice graphics, simple to understand gameplay, but it has several bugs that made the experience bad for me, to start with the upgrades suddenly change and for the worse when you are already on top (I think maybe there is a change in the object and it affects all instances), when you change screens you appear directly on an upgrade, if you are unlucky it is on the bad one, it should not change the scenario with the newly picked object but wait a bit to avoid it.
But nice.
P.S.: In my game I have a minigame that also has the WS mechanic to move XDXDXD
