This one takes me back to the flash game era. I'm not sure why exactly... I just felt reminded of flash games and this really felt like a fully fledged game, very impressive for a jam game! A nice tutorial, very simple but also kinda strategic and difficult gameplay, persistent upgrades, nice clear visuals, really really nice work! Ohhh I think it might be Bubble Tanks that I'm kinda reminded of.. I mean it's quite different, but there's something kinda similar too. Awesome work :)
