This is the first game of this jam that I actually beat because it was proper fun the entire way through and didn't get boring midway. I am rating everything fairly as I can and I gave you 5 stars on all 4 metrics. You earned it. The game is fun, it nails the theme, it's original (yes it's a RTS genre but, it's done very unique way) and the presentation is top notch. Everything looks and feels good. The mechanics and tooltips were so well done that I didn't need a tutorial, but you made a tutorial anyway, and bonus points to you for that. This should be a full game. Add some more stuff to it and sell it for $5-10 bucks on steam.
If you were to make it a full game:
- more difficulty modes (it was a bit easy)
- more monster types (maybe with range or something)
- more building types, i had way too much power and nothing really to build. think of more risk reward situations, you should have to choose between generating more power with a risk OR being safe with a turret. the game is sort of set up that way, but the balance right now, i was never in danger of running out of power. or maybe my strategy was just genius. factorio is a good thing of something to look at where you have tons of different buildings researching different things and needing different resources. but dont make it that complicated because that hurts my head. lol.
- more upgrades/tweak upgrades (i never used the rock upgrade for the turret as i had so much power that building wires to them was trivial)
- add some blocking terrain, rivers, mountains, stuff like that
- bigger map with ability to move and zoom in and out, so you can expand bases
- story and objectives (think of starcraft missions, one mission might be to rebuild generators at a damaged base, and one mission might be to wipe out 5 nests, and one might be etc etc.) and a little sauce with like, you're on this planet and your name is commander bigpants and you are trying to colonize this planet but you have to wipe out the alien bugs first etc etc.
Unrelated note but as a developer, my game was surprisingly similar to yours, but mine was units instead of buildings. Maybe you'll dig it lol. Mine is much uglier though and the explanation of mechanics is not nearly as good. Again props to you on that.
