Could you please put this on Steam for 10 Bucks or so and then continue to develop it? Would be a shame if it stays at 5 levels forever and 2$ isnt a price you should be offering :)
It has great potential, but in the current state 2$ is a fair price. If you think it should be more you can always buy it again or pay a higher price on itchio. Steam might give more exposure but has also the risk of people abandoning the game or giving bad reviews due to its unfinished state
