Hey, I did couple of loops, it's very easy to level up and to be unstoppable killing machine, I think that by 5th loop enemies couldn't approach me at all. Plasma can be upgraded only to level 4, even though you can still select it to upgrade. Also the pattern the orbs are staying is weird, should it be like that? 

Teleporter to spawn boss enemy is moving between loops, I think it's fine but it spawned in the air couple of times, one time in a very awkward spot and at the end spawned probably outside of a map.

Got pushed into the terrain by the moving platform and there's no way to escape. Enemies still could't touch me though. I saw one enemy going fast left-right just above me, I guess you're using basic pathfinding, something fancier could be much more fun.

I have to say that autoattacking makes it dull for me, but I'm a little allergic to vampire-survivorlikes. In that sense I don't really have any advice other than making more enemies, making them more aggressive, adding more upgrades and after that... it might still not be that interesting. 

Another idea, if anything, going full-customisation mode might be better - scavenging for parts of the equipment, having weight limits and size limits for different weapons, improving these stats to install more mods and so on. Satisfaction from building your own mecha suit and then unleashing it onto the hordes of enemies can be much more appealing, after that killing enemies is just a test of your build and I know for a fact there's plenty of people craving just that.

So yeah, ideaguying and backseat-talking aside, I'm looking forward to see how the project progresses.

Froze the game in the second area. Had a chest that didnt disappear on pressing down. Held down for a while, wanted to click an upgrade and the game was stuck.

Really cool polish since the last times. I like how the xp orbs now have gravity and its easier to collect them. The player sprite compressing on landing is cool too. I think the chests are new, thats good too. I dont understand those litte plants or flails (i think they look like little flails). Levels look and feel more like levels.
Keep it up!

at first I didn't understand what was happenning with the xp orbs and enemies dying on their own, because there are no attack animations or vfx. 

I played a bit but there isn't much to do. I tried colliding with the boss to see the rate of damage etc but only managed to lose 1 hp before he died.  you want to change the immunity timer or something.  fullscreen would probably be better than windowed, if you can't get in settings by the next time.
Moving platforms can push you into terrain.

I got through about  4 teleporters.  I see the risk of rain influence, but it needs a lot more time to bake before it can compare.  That said, I do think risk of rain is a good learning game to copy, as a project to learn an engine or making one.

A big thing is working on clarity for the player.  Like for the laser, it'd be good to have some feedback on the player that tings are firing.  Also different sprites for the laser impact, and the orbs that orbit you. Just stuff like that that makes it more clear about the action -> reaction that comes from players actions.
