Pretty cool and simple to understand, thank you :) I have the feeling that the damage increase it not very efficient, so I go for range and shield. Is it just me ? If not, maybe you should rebalance the stats of your upgrades ;)
That actually makes me really happy to hear. Playtesters were saying they only spent points on damage and range. So hearing you spent points on armor and range, says maybe it's less "obvious" of a choice than I thought it was.
Oh really ? Ok, so maybe it's alright. But be aware that I have only played few times. And thank you for all the work you done for Gdevelop community too ;)
